are you antithesis from xim forum?
Almost all wired mice and keyboards are compatible, and even power-hungry mice such as the Corsair Nightsword RGB can be used without any problems. the aim assist can be individually adjusted via the values for steps and radius in the game profil. use the right mouse button as a hotkey. if a mouse or keyboard, whether wired or wireless, does not work, support will quickly enable compatibility.The polling rate of the S1 can easily be set in the global settings of the S1 (125, 250, 500 and 1000hz) after confirming with ok the S1 restarts by itself. Only the app on the smartphone has to be closed and restarted manually. This has the advantage that the USB port of the console is spared. This is very practical and well implemented. however, it must not be forgotten that these are different adapters with different engines. I personally think both adapters, Xim Apex and S1, are equally good. Both development teams are great.
here is the link to the manuals:
