Answer 1

You missed the most important part:
const Massage = await new Movie({
title: "The Massage",
year: 1976,
score: 92,
}).save();

Answer 2

The problem is that I did not set a collection in the model
so instead of
const Movie = new mongoose.model("Movie", movieSchema);
it should be
const Movie = new mongoose.model("Movie", movieSchema, collectionName);
when you want to extract the data from database
use database // go to the database u want
db.collection.find() // extract the data from the collection
