addon touchscreen on LE10.0.3

Hello.
I installed libreelec 10.0.3 in order to make my touch screen work in HDMI type waveshare 10.1".
I installed the touchscreen addon but this one does not work. Everything worked fine with LE9.2.8 so I took the same settings in ts.conf and ts_env.sh
The driver that manages the touchpad is an "egalax", the screen is 1024X600. The raspberry is not connected to the screen by the pins.
Has anyone managed to get this device to work with LE10.0.3?
