WiFi Guest pending administrator approval

Hello, We are deploying Fortinet WiFi (Fortigate, FortiAP and FortiAuthenticator). I have seen a feature for guest users in other vendor solutions where a new WiFi guest user request access and the login access wait the approval of an administrator to connect directly to the WiFi network. I would like to know if this feature is available in the Fortinet WiFi solution.

Steps would be:

1) New guest request acces

2) Guest login screen is waiting for approval

3) Administrator approves request access

4) Guest login screen get connected automatically.

Please let me know if you understand this scenario.

Thank you very much!
