Google health requires app verification when the integration has more than 100 users, so sorry to inform you, but at this point we are not planning to go forward with the app verification. The security assessment sounds time and money consuming and it needs to be done annually.
Intervals has been security audited and penetration tested, but they are not done with Cloud App Security Assessment framework (CASA) in mind.
Personally, I feel like this integration needs to be done in the future (what ever that means), but at this point we have no plans for it
