[avstream::avssamp] Neither graphEdit nor third-party apps can find avssamp

https://github.com/microsoft/Windows-driver-samples/tree/main/avstream/avssamp

I am using vs2022 to build sample of avstream whose name is avssamp.

I successed to install it by devcon. Then it can be found in "Camera" of device manager.

However, it can not be found by GraphEdit in [WDM Streaming Capture Devices].

Besides, it can not be recognized by OBS, ZOOM, and so on.

I have confirmed the driver has been installed normally by "pnputil /enum-drivers".

I found that many people are asking this question but has no available answer.

Can you help ?
