how to implement verify Request in Credential Provider

No option for verify request in Credential Provider

Doc said:

Email accounts do not have profiles in the same way OAuth accounts do. On the first call during email sign in the profile object will include an property verificationRequest: true to indicate it is being triggered in the verification request flow. When the callback is invoked after a user has clicked on a sign in link, this property will not be present.

I want to implement verify request in Credential Provider but I don't know where to add this verificationRequest: true .
Right Now, Only Email Provider has this verify request .

Is it possible to implement verify request in Credential Provider?
