I see that this is not supported in com.google.android.gms.fido.fido2.api.common.AuthenticationExtensions, but it seems to be supported when building PublicKeyCredentialCreationOptions from JSON as I clearly see it in the source of the play-services-fido-21.1.0 lib and it's also working in Chrome.

FxA are looking to use PRF as part of Passkey support that they are adding and from the MDN docs, it looks like Android is missing support, which links to this bug.

Hey John, do you know what the priority of this would be?

We'll get this "for free" with Bug 2008744. I should be able to get it done for 149.
