android:name="com.vizua.launcher.UnityPlayerActivity" is the right Activity path and matches the "Player Settings > Others Settings > Identification > Package Nale" in Unity.
Thank you for reaching out to the Publishing Support Team.
Our team handles developer focused issues with platform services and developer application support.
Opening applications must be from the direct application itself. Opening an Oculus Quest application from Oculus Browser (deep link) is not supported at this time.
We can let our internal teams know that this is a feature request, but as of right now this is not supported.
If you wanted a more detailed response, we now have a dedicated technical support team on the VR Developer forms and they can better support your question/request there.

This is the latest answer I got from the support. Still an answer from the internal Team would be really appreciated. Why this is not supported?
