I've been using the Nintendo Switch joycon in linux, but they require some manual mapping and axis needs to be inverted when used in split mode

Describe the solution you'd like

I would like a way to invert the direction of the axes (e.g. moving from left -> right becomes right -> left and same for vertical axis)

Describe alternatives you've considered
