using this schema

const UserSchema = new mongoose.Schema({
  username: String,
  fName: String,
  lName: String,
  title: String,
  hash: String,
  salt: String,
  admin: Boolean,
  chats: [{ userid: String, messages: [{ user: String, message: String }] }],
});

what is the correct way to find a "_id" along with a specific "userid" using Model.updateOne()?

    User.updateOne(
      { _id: data.receiver, chats: { userid: data.sender } },
      { $push: { chats: mes } },
      (err, result) => {
        if (!err) {
          console.log(result);
        } else {
          console.log(err);
        }
      }

this ^^^^ doesnt work but this

    User.updateOne(
      { _id: data.receiver },
      { $push: { chats: mes } },
      (err, result) => {
        if (!err) {
          console.log(result);
        } else {
          console.log(err);
        }

finds the correct user
