python - Firestore - Nested query

Question

I'm really new to firebase and to be honest I find queries hard to write. I'm working on a script in python using firebase_admin and i'd like the query/answer to be in python code, but in any other programming language is fine.

Here's my one of my document, one document contains photos set

photos: {
    id1: true
    id2: true
}

I want to be ale to retrieve all items where they have id1 in photos object, what would be the query for that?
