VERIFICATION_STATUS_UNSPECIFIED (0):
Sentinel value used to indicate that the

(as in the case of channels that neither support
nor require verification in order to function).
UNVERIFIED (1):
The channel has yet to be verified and
requires verification to function. Note that
this state also applies to the case where the
verification process has been initiated by
sending a verification code but where the
verification code has not been submitted to
complete the process.
VERIFIED (2):
It has been proven that notifications can be
received on this notification channel and that
someone on the project has access to messages
that are delivered to that channel.
