javascript - Is there a way to query for a Firestore collection to get the number of times a field's value occurs?

What I am trying to do is to query a Collection in such a way that:
1. I can get the number of times the value true occurs in all documents
enter image description here

Like, is there a way to check through each document and query for document fields matching true ?

  1. After that, store the number of times that true value occurs in a variable.
