Yep, get a Titan Two.
Xim will only ever be capable of passing through key or button presses bound to game actions. A Titan Two on the other hand has multiple USB ports that allows for either the mouse & keyboard to be connected to the T2, then onto the Apex. Or Apex in one T2 port and a kb in another. What that provides is the ability to bind keys to macros that are separate from in-game actions.
