Not able to get the GetGuestNetworkPassword trait work on the router device

[Jerome1998]

I'm currently working on integrating my FritzBox router with the Google Smart Home App. I've successfully connected various local devices, such as my computer as a Gameconsole, to the app using an API on my NAS.

The integration is working smoothly for all functionalities, including enabling/disabling the guest network, speed tests, etc. However, I'm encountering an issue with the GetGuestNetworkPassword command.

Problem Description:
When I attempt to access the guest network settings on my Google Nest Hub 2 device, I get prompted to enter my PIN. After entering the PIN, the loading square appears, the guest network password as a QR code should be displayed. Unfortunately, the loading never completes.
