Guide for getting better results from airpods pro 2?

So I picked up a set of airpods pro 2 buds to see if they might be useful in HA mode for around the house when I’ve already removed my HAs for the day (because of evening workout or something). Initial result sucked. Lots of squealing from feedback (not constant, just little spurts of it as I move) unless I truly jam them into my ears. Is there a good website someone has seen with tips for optimizing their settings and input of Audiogram to get a better result? I mean they are a great purchase regardless even without turning on the HA mode but I would like to get them to be at least reasonably usable in HA mode if I can.
