Someone set up Matterbridge to transfer the contents of a Telegram channel into a Mattermost channel. To do this, they created a Telegram bot.
Unfortunately, the person has disappeared (Covid?), and we don't have full details of the account used to set up the bot.
We do have the Bot Token (from the Matterbridge config file).
Is there any way we can find out more about the bot, change its settings, join it to other channels, etc?
