Get all documents where an attribute in map within an array matches condition in firestore?

Question

Im new with firestore and nosql, i have this structure..

What I am trying to do is to write a query where I can filter documents based on 'exercise_id' within a map inside the 'exercises' array. How would I go about doing this, I have had a look at firestore documentation with no avail. Is this even possible? Or is my structure wrong here...

Any help is appreciated. Thanks!
