Pico neo3 in unreal 5.2 input mappings

Hey im currently developing a vr game in unreal 5.2 with a pico neo3 headset. So far ive created a functioning game i which i can see the controllers and turn around 360° but im having problem with the input mappings. Ik that there are Enhanced Input Mappings for PICO in UE 5.2 Input mappings | PICO Developer but if i copy them in ue non of them work im using this video https://www.youtube.com/watch?v=WxtzBFVtHJc. Could that be bc i have a pico neo 3 insted of a pico neo4? and if yes how can i fix it. ive already tried the pico open xr plugin but i cant package the project with both pico xr and pico open xr plugin enabled (they dont work at the same time and the pico xr plugin is essential for the vrpawn) . Please help its rlly depressing
