(Going from memory) we used firebase and had access to the native authentication SDKs, then we we switched to ory, we had to hack it back in because the documented way to implement ory would have used browser authentication. Ory provides a javascript bundle you load to do webauthn, which (again IIRC) didn't work inside the browser inside the app, and although we figured out some workarounds, would have conflicted with how we implemented the native auth.
