How to navigate through documents in a circuler linked list fashion in MongoDB?

Question

I have a really simple User model.

const userSchema = mongoose.Schema({
  name: {
    type: String,
    required: true,
  },
  email: {
    type: String,
    required: true,
  },
  password: {
    type: String,
    required: true,
  },
  address: {
    type: String,
    default: null,
  },
  description: {
    type: String,
    default: null,
  },
  active: {
    type: Boolean,
    default: true,
  },
  interests: [
    {
      type: String,
      default: null,
    },
  ],
  favorites: [
    {
      type: mongoose.Schema.Types.ObjectId,
      ref: 'User',
      default: null,
    },
  ],
});

I have a use-case where the client should be able to navigate through the users one by one in a circular fashion. I was able to implement the functionality for getting the next and previous user relative to a specific user through the this answer. However, the issue with this is that if I try to get the previous document on the first document in the Users collection, it of course returns an empty object. And same is the case when I try to get the next document on the last document. I want to tweak it so that if I try to get the previous document on the first document, it would return me the last document, and if I try to get the next document on the last document, it would return me the first document. Just like how you traverse through a circular linked list.
Any help would be appreciated! Thanks.
