javascript - Firestore update all documents in collections

I have a firestore collections named users, each users have a generated id with a field score :

users 
    0e8X3VFL56rHBxxgkYOW
        score : 4
    3SeDjrgAWMmh3ranh2u
        score : 5

I use redux-firestore and i want to reset all my users score at 0, something like

firestore.update({ collection: 'users' }, { score : 0 }

I can't achieve this because update method need a document id

Do you know how to do this ?
