Ndkroot is not specified

I have been trying to make a vr game with UE.2.5.4 and I am trying to do so with the oculus quest 2, I found a youtube video tutorial and followed all of the steps and when I launch the game through my quest it says “ERROR: NDKROOT is not specified; cannot use Android toolchain” in the out put log. i have tried everything and nothing works, can someone please help me.

Hi, I have the same problem as you, did you solve it?
