Your mixer has what’s called “global phantom power” meaning one switch for all phantom. You shouldn’t have any issues with feeding a wireless into a mic input with phantom power on. It’s not reccomended but it won’t hurt anything. If you have a non powered line input module on your mixer you could try turning up the wireless receiver output to the max and plugging it in there and see if that works for you. You’ll need a different output cable, most likely 3.5mm trs to 1/4″ trs.
