The accepted-name answer pushes it, so its enter sends nothing. The person
types the username they want; submitUsername sends username.async and
moves to the terms screen. A taken or invalid username is the typed
RegistrationUsernameTakenError and the screen stays on top. The action also
requests the attestation nonces the account creation reports: the Play
Integrity nonce before the submission and the keystore nonce after it, the
recorded order.
No screenshot: the frame needs a registration that reached this step.

that closes it is an Android 451 app registering a new account from the login
homepage.
