BEST set up

Good evening, the keymander 2 has arrived and I have been able to configure it on ps5 with a ps5 controller. With the help of the beloader pro adapter, I play with and mouse on ps5 to battlelfield 2042 but I don't know how to configure the dead zones, sensitivity, on the mouse and in the game, x/y sensitivity. Can you please help me I am very happy with this adapter but I can't get everything to go well in the game, thank you very much
