How to manage Device ID with local couch gaming?

Hello,
Am trying to buid a local multplayer game.
After a lot of brainstorm, I manage to put 2 player on the same keyboards with the Enhanced control system.
I am now trying to have player 1 and player 2 in local on a joypad, but when I try, this put the two players on joypad one.
I believe my solution is to be able to define which device ID I should target for player 1 and 2 , but I do not know how to do it…

Here are my different file:

player controller
-Player1


-player2

Input system
-to move forward

Assignation of the mapping:

Any help is really appreciated.

Maybe you need create a new player controller first!
