Is there a way I can search for a message by its id in Discord.JS?

Question

I've been searching throughout Stack Overflow for answers, but I can't find a way to get a message by its id in multiple channels.

Basically, I'm trying to make a reaction role command using Discord.JS v14, but I can't be guaranteed that everyone who uses the bot is going to use it in the same channel the message is in. I've tried using .forEach() but it doesn't work.

Here's my code:

const {
  SlashCommandBuilder,
  PermissionFlagsBits,
  EmbedBuilder,
} = require("discord.js");
const { enabled, disabled } = require("../../../config.json");
const Settings = require("../../schemas/settings");
const mongoose = require("mongoose");
const Reaction = require("../../schemas/reactionRole");

module.exports = {
  name: "reaction",
  description: ``,
  category: "Utility",
  data: new SlashCommandBuilder()
    .setName(`reaction`)
    .setDescription(`Modify or setup reaction roles in your server!`)
    .setDefaultMemberPermissions(PermissionFlagsBits.ManageRoles)
    .addSubcommand((subcommand) =>
      subcommand
        .setName(`setup`)
        .setDescription(`Setup reaction roles in your server`)
        .addRoleOption((option) =>
          option
            .setName("role")
            .setDescription(`Specify a role you want to use`)
            .setRequired(true)
        )
        .addStringOption((option) =>
          option
            .setName("message-id")
            .setDescription(`Enter the message's id`)
            .setRequired(true)
        )
        .addStringOption((option) =>
          option
            .setName(`emoji`)
            .setDescription(`Specify the emoji's id`)
            .setRequired(true)
        )
    ),
  async execute(interaction, client) {
    switch (interaction.options.getSubcommand()) {
      case `setup`:
        const role = interaction.options.getRole(`role`);
        const msg = interaction.options.getString(`message`);
        const emoj = interaction.options.getString(`emoji`);
        const emoji = client.emojis.cache.get(emoj);
        const message = interaction.channel.messages.fetch(msg) //How can I replace this?

        const notEmoji = new EmbedBuilder()
          .setTitle(`Invalid Emoji Specified`)
          .setColor(`Red`)
          .setDescription(`The emoji id you specified is not valid`)
          .addFields({
            name: `How to get emoji id:`,
            value: `To get an emoji's id, you first type it as usual:\n:smile:\nTo get it's id, you add a backslash (\\) to it, as such: \:smile:\nThe number is what you use as the id.`,
          });

          const notMessage = new EmbedBuilder()
          .setTitle(`Invalid Message Specified`)
          .setColor(`Red`)
          .setDescription(`The message id you specified is not valid`)
          .addFields({
            name: `How to get message id:`,
            value: `To get a message's id, you hover over it whilst clicking shift, then a number of icons will appear, click on the ID icon to copy the id of the message`,
          });

        if (!message) return interaction.reply({ embeds: [notMessage] });

      
        
        const m = await interaction.channel.messages.fetch(message); //How can I replace this?
        m.react(emoji);

        await new Reaction({
          _id: mongoose.Types.ObjectId(),
          guildId: interaction.guild.id,
          messageId: message.id,
          emojiId: emoji.id,
          roleId: role.id,
        });

        break;

      default:
        break;
    }
  },
};

People in the comments have mentioned that this is not possible, however, I have been experimenting with Discord IDs lately and found that it is possible. A user can copy a message's ID by pressing the Shift key on their keyboard, hovering over a message, and clicking on the ID icon. This way, the copied ID contains two parts, something similar to this: 123456789123456789-123456789123456789.

The first part of the ID is actually the channel's ID, in which the message has been sent, whereas the second part is the message's ID. The only downside to this is that this is only the case for users copying a message's ID, but not a bot. The bot will simply just receive the second part.

However, since my case only needs the user to copy the message ID, I think I could do something like this:

const args = msg.split(`-`); // Splitting the string into an array

const channelId = args[0]; // The first element of the array
const messageId = args[1]; // The second element of the array

const m = await client.channels.cache
.get(channelId)
.messages.fetch(messageId); // Searching the client for the channel, and the message in that channel
// Code below

Please note, when you right-click on a message and copy the ID, the copied string is the message ID only. It doesn't include the channel ID. Pressing Shift, hovering over the message, and clicking the ID icon doesn't require the Developer mode to be turned on either.
