M365, Entra ID, Google Password Manager Passkeys

I went into my tenant, opened the Entra ID Admin, and enabled passkeys (fido2) authentication.  I want to use Google Password manager since it will work across al my devices/platforms (Windows, Mac, Android, iOS). 

I went into the security settings for Microsoft 365 account to add an authentication method.  I am happy to say that "passkey" is listed as an option, so I created a new passkey in Google Chrome/Password Manager and named it after my userid in the tenant.  To test it, I logged out and attempted to log in using the passkey.  The option came up, but Microsoft complained it was not a valid key.  I tried again stating that I would my phone for the key and scanned the QR code but my phone said there is no passkey I would need to create one.  How do I solve this?

BTW: I did add Google's AAGUID in the Entra admin and allowed it but that did not solve the issue.
