Quest 2 Hand tracking on Standalone mode (UE 4.26)


I am currently using Unreal Engine **4.26 **and for some reason there is one level I can only launch in standalone mode (VR preview is not ok because I have to switch from a 2D level to a VR level).
The problem is that the Oculus VR plugin’s hand tracking seems to be working only in VR preview.
In Standalone mode, the headset recognises my hands as they trigger system gesture but they won’t appear on the screen nor do anything that I’ve implemented.
Has anyone got a solution for this ?
