Browser support on iPad is not clear for FIDO2

Hi All,

I am trying to use FIDO2 security keys to login into MS accounts using NFC transport on latest iPad OS 17.2 but seems like there is no support by Microsoft yet. I couldn't find anything on below compatibility matrix:

https://learn.microsoft.com/en-us/entra/identity/authentication/fido2-compatibility

even though I was able to login with FIDO2 NFC keys on other identity provider websites like Okta using Safari as well Chrome on iPad.

Does anyone know if it not supported officially? I can't find any information on iPads anywhere.
