Finding a nested document and updating it accordingly

I’m trying to create a method for updating a single document.
The following is my query:

  const {
    assetId,
    editAssetData,
  } = req.body;

    const newAsset = await Catalog.findOneAndUpdate(
      { 'assets._id': assetId },
      {
        $set: {
          assetName: editAssetData.assetName,
          assetQuantity: editAssetData.assetQuantity,
          singleQuantityPrice: editAssetData.singleQuantityPrice,
          totalQuantityPrice: editAssetData.totalQuantityPrice,
        },
      }, (err, asset) => { (err) ? console.log('err=>', err) : console.log('asset=>', asset); },
    );

    const asset = await newAsset.save();

console.log(asset) just returns the catalog document, to which the asset is a nested element.

This is what my model looks like

const catalogSchema = new Schema({
  assetType: { type: String, required: true },
  description: { type: String, required: false },
  creator: { type: Schema.Types.ObjectID, required: true, ref: 'User' },
  assets: [{
    assetName: { type: String, required: false },
    assetQuantity: { type: Number, required: false },
    singleQuantityPrice: { type: Number, required: false },
    totalQuantityPrice: { type: Number, required: false },
  }],
});
