Laravel 5.8 email verify with multiple guards

I am trying to add verify email function in Laravel 5.8 i have 2 custom guards and need email verification for both guards. I am successfully verifying it for first guard but for 2nd guard verify email is not working.

here is verification controller.

public function __construct()
{
    $this->middleware('auth:guard1');
    $this->middleware('signed')->only('verify');
    $this->middleware('throttle:6,1')->only('verify', 'resend');
}

if i add another line of $this->middleware('auth:guard2'); in construct function both of my verifications are not working. can any one help me here how to send verification email for multiple guards and verify their emails ?

Thanks
