Mongoose - Get and Delete a subrecord - node.js

Question

I have a model defined as so:
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const feedbackSchema = new Schema({
Name: {
type: String,
required: true,
},
Email: {
type: String,
required: true,
},
Project: {
type: String,
required: true,
},
Wonder: {
type: String,
required: true,
},
Share: {
type: String,
required: true,
},
Delight: {
type: String,
required: true,
},
Suggestions: {
type: String,
required: true,
},
Rating: {
type: String,
required: true,
},
dateCreated: {
type: Date,
default: Date.now(),
},
user: {
type: Schema.Types.ObjectId,
ref: 'User'
}
});
const UserSchema = new Schema({
googleId: {
type: String
},
displayName: {
type: String
},
firstName: {
type: String
},
lastName: {
type: String
},
image: {
type: String
},
createdAt: {
type: Date,
default: Date.now(),
},
feedback: [feedbackSchema],
})
module.exports = mongoose.model("User", UserSchema);
An example document:
{
_id: ObjectId('60b9dc728a516a4669b40dbc'),
createdAt: ISODate('2021-06-04T07:42:01.992Z'),
googleId: '2342987239823908423492837',
displayName: 'User Name',
firstName: 'User',
lastName: 'Name',
image: 'https://lh3.googleusercontent.com/a-/89wf323wefiuhh3f9hwerfiu23f29h34f',
feedback: [
{
dateCreated: ISODate('2021-06-04T07:42:01.988Z'),
_id: ObjectId('60b9dc858a516a4669b40dbd'),

},
],
__v: 0
}
I have two routes defined, the first one is called when the user clicked a button on a feedback item on the UI which takes the user to a "are you sure you want to delete this record"-type page displaying some of the information from the selected feedback record.
A second route which, when the user clicks 'confirm' the subrecord is deleted from the document.
The problem I'm having is I can't seem to pull the feedback from the user in order to select the document by id, here's what I have so far for the confirmation route:
router.get('/delete', ensureAuth, async (req, res) => {
try {
var url = require('url');
var url_parts = url.parse(req.url, true);
var feedbackId = url_parts.query.id;
const allFeedback = await User.feedback;
const feedbackToDelete = await allFeedback.find({ _id: feedbackId });
console.log(feedbackToDelete);
res.render('delete', {
imgSrc: user.image,
displayName: user.firstName,
feedbackToDelete
});
} catch (error) {
console.log(error);
}
})
Help much appreciated

Update
You should be able to do just this:
const feedbackToDelete = await User.feedback.find({ _id: feedbackId });
Or if feedbackId is just a string, which is appears to be, you may have to do something like:
// Create an actual _id object
// That is why in your sample doc you see ObjectId('foobarbaz')
const feedbackId = new mongoose.Types.ObjectId(url_parts.query.id);
const feedbackToDelete = await User.feedback.find({ _id: feedbackId });
Original
Shouldn't this:
const allFeedback = await User.feedback; (a field)
be this:
const allFeedback = await User.feedback(); (a method/function)
?
