With the Q2 you won’t need WMR. You do have a choice to either run through oculus native or steamVR.
There’s a welcome guide here:
If looking at guides on YT just make sure the guide is specific to Q2. VRflightsimguy has done some for this I believe.
Also, MSFS runs slightly different to other VR games. It uses openXR, so therefore just because you own it on steam does not mean you need to use steamVR.
Good luck! And welcome to MSFS VR!
