Android only.
Used to assert application identity in place of a recaptcha token. At
least one of (ios_receipt and ios_secret), recaptcha_token, or
safety_net_token must be specified to verify the verification code is
being sent on behalf of a real app and not an emulator, if
'captcha_response' is not used (reCAPTCHA enterprise is not enabled). A
SafetyNet Token can be generated via the
SafetyNet Android Attestation API,
with the Base64 encoding of the phone_number field as the nonce.
