I'm trying to access data from a firestore document, but I'm getting an error message that exercise.data() is not a function. I don't understand how the exercisesToAdd array is an array of documents, but I can't use .data() to get the contents of the items? How else would I go about getting the data from those documents?

I know the exercisesToAdd array is actually being filled with documents because I see them in the database when I send the array. Seems straight-forward but I must be missing something.

chosenExercises.forEach((exercise) => {
    exercisesToAdd.push(doc(db, 'Users/' + auth.currentUser.uid + '/Exercises/' + exercise));
});

exercisesToAdd.forEach((exercise) => {
    console.log(exercise.data());
});
