Hi! In my app, users can create a subject to make a photo album for, so the database is set up like Users -> Subject, and then subject has a field that's images_of_subject and it's a <List> Image Path.
I'm trying to make it so a user can update a document by tapping a button to upload multiple photos, and then the field images_of_subject gets updated to have that list of photos.
I tried following the tutorial here: https://docs.flutterflow.io/actions/actions/backend-database/firestore, but my version of FlutterFlow doesn't match the part where they click on Firestore > Update Record and set Source to the Parameter Name that holds the record. Instead, I just get this screen that I attached. Please help me figure out how to update a document in Firestore.
