Unable to patch Unity based Apps

[DeltaPy]

Hello,
I'm trying to patch a Unity 3D VR app for the Meta Quest, but after executing .\modder.bat patch -m .\downloaded-app-folder
the script responds with "Cannot find launchable activity from apk".

I tried modifying the Patcher.kt code and setting val launchableActivity = "com.unity3d.player.UnityPlayerActivity" after building the project and running the patcher again, it runs into a NullPointerException (output below).

Output:
I: Using Apktool v2.9.0-22-bea15e6f-SNAPSHOT on base.apk I: Copying raw resources... I: Copying raw manifest... I: Baksmaling classes.dex... I: Baksmaling classes2.dex...

The launchableActivity that I setted is probably wrong. If someone can please explain to me what is the expected output of the LaunchableActivityToSmaliRelativePath() function in Patcher.kt, I can try to make it work as I can't find enough information online.

Thank you!
