Try as I may, I cant find any way or reason the 1922 mandate is even remotely relevant. It never was and never will be binding on anyone. Even if it had ever been in any way agreed, it was never implemented and has long been superseded by later developments. You just like to look around for dead non-agreements that were never implemented and give them legitimacy you deny actual resolutions and international law. Enjoy your fantasies, but dont mistake them for anything real. No one else does.
