Oculus Developer Hub: My Device > Apps > APK is not installed - nothing happens

Dear community,

I am working with an APK developed by a developer in our team. In the Oculus Developer Hub application on Windows 10,  I select the Quest 2 under My Device, select Apps and "Upload" in the field "Upload an APK", select the APK (as described in Deploy Build on Headset | Oculus Developers) and then the following modal is shown for about 5 seconds:

After a few seconds, the modal disappears and the list of applications stays empty, even after 30 minutes:

The computer is connected to the Quest 2 with the USB-C cable and the Quest 2 is turned on.

Please let me know how I could install the APK on the Quest!

Thanks in advance!
