For Xbox consoles you dont need remote play as the XIM works directly with the consoles. Sony Remote Play only works with PS consoles too.
Odin how come ps5 comtroller is works on remote play is it something known ?
Im not sure about that tbh, for some people the PS5 controller works through Remote Play but for other users it doesnt. Its probably a combination of using the latest XIM Firmware, PS5 controller firmware and Sony Remote Play firmware. Also there seem to be differences between Windows and Mac users.
