I also don't have a ps5 I only have the controller :'( ^_^.
If you mean the face buttons then they are numbered like so : from 1 to 4 Square - Cross _ Circle _ Triangle , the opposite of what they be on pc controllers.

I put in a support ticket to see if I can get some more info but in the meantime I may have found a workaround if you would be willing to try it for me. I've uploaded a build with mouse view and limited debug menu, when on title screen press F1, in top left corner click settings/operation settings then select your device and change the dpad inputs there.
