Android support for DevicePubKey extension

[thomasnymand]

I am having issues testing the use of the DevicePubKey proposed extension (DevicePubKey) that seems to be supported (although the documentation for AuthenticationsExtensionsClientInputs.DevicePubKey is misleading). UserController enables this extension.

I am not able to retrieve any extension responses from neither create() nor get() methods when passing this extension to client where support should be enabled (Chrome on recent Android, cf. Security of Passkey in Google Password Manager ).

Does anybody have experience in using this extension successfully?
