Investigate the one to many relationship in MongoDB

Is there a way to retrieve a document with one-to-many relationships in a query? When I attempt to do so, I receive the object ID as a reference, but I actually want the full document.

await Schedule.find({});

This code snippet returns:

"schedule": [
        {
            "_id": "63a4b45275be846cf3ed135d",
            "date": "2023-01-01T23:00:00.000Z",
            "timeSlots": [
                "63a4b45275be846cf3ed134c",
                "63a4b45275be846cf3ed134d",
                "63a4b45275be846cf3ed134e",]

It currently only returns the object ID, but ideally, it should return:

 {
    _id: new ObjectId("63a4b45275be846cf3ed134c"),
    slot: '11:00',
    isBooked: false,
    isCompleted: false,
    service: 'HAIRCUT',
    __v: 0
  },
  {
    _id: new ObjectId("63a4b45275be846cf3ed134d"),
    slot: '11:30',
    isBooked: false,
    isCompleted: false,
    service: 'HAIRCUT',
    __v: 0
  },
  {
    _id: new ObjectId("63a4b45275be846cf3ed134e"),
    slot: '12:00',
    isBooked: false,
    isCompleted: false,
    service: 'HAIRCUT',
    __v: 0
  },
  {
    _id: new ObjectId("63a4b45275be846cf3ed1353"),
    slot: '14:30',
    isBooked: false,
    isCompleted: false,
    service: 'HAIRCUT',
    __v: 0
  },
  {
    _id: new ObjectId("63a4b45275be846cf3ed1351"),
    slot: '13:30',
    isBooked: false,
    isCompleted: false,
    service: 'HAIRCUT',
    __v: 0
  },

Instead of just displaying the object ID.
