    service cloud.firestore {
      match /databases/{database}/documents{ 
          //define the database variable, use it later as $(database)
        match /patients/{patientId}{
            //define variable patientId, use later as $(patientId)
            allow read, write: 
              // if exists(/databases/$(database)/documents //WORKS
              //    /patients/$(patientId)
              //   /permissions/$(request.auth.uid))
              if get(/databases/$(database)/documents //WORKS
                /patients/$(patientId)
                /permissions/$(request.auth.uid)).data.write == true;
         //you have to get(...).data.myProperty 
    }
    // match /{document=**} {
    //  allow read,write: if false;
    // }
