Populate document with other fields

I got the following document:

{
"_id": "5b5df332879b4769739e3ed0",
"name": "Back workout",
"exercises": [{
"_id": "5b5df9a7879b4769739e3ed1",
"results": [{"reps":"10","weight":"85"}, {"reps":"8","weight":"70"}]
}]
}


I want to populate the exercise based on the _id and also append the results data.

_id

results

Expected output:

{
"_id": "5b5df332879b4769739e3ed0",
"name": "Back workout",
"exercises": [{
"_id": "5b5df9a7879b4769739e3ed1",
"name": "EXERCISE_NAME",
"results": [{"reps":"10","weight":"85"}, {"reps":"8","weight":"70"}]
}]
}


My Schema looks like this:

const WorkoutSchema = new Schema({
_id: Schema.Types.ObjectId,
name: String,
exercises: [{
_id: { type: Schema.Types.ObjectId, ref: 'Exercise' },
results: Array,
}],
createdAt: Date,
updatedAt: Date,
});
