How to replace the Touch Pad of laptop Chuwi GemiBook 13"

Hi ! I have a LAPTOP Chuwi GemiBook Type CW1528. It is upgraded now with Windows 11 Version 22H2 and has the following Specification : Device name DESKTOP-NOU5ETS
Processor Intel(R) Celeron(R) J4125 CPU @ 2.00GHz 2.00 GHz
Installed RAM 12.0 GB (11.8 GB usable)
Device ID 73234DFE-6165-426E-8F1A-5820CA81FA46
Product ID 00325-80000-00000-AAOEM
System type 64-bit operating system, x64-based processor
Pen and touch No pen or touch input is available for this display

I was very happy with the purchase of this Laptop, but now I have a technical problem with it : the MOUSE RIGHT CLICK FUNCTION, press located at the RIGHT DOWN CORNER of the TOUCH PAD don’t work more since ca. 1 Month. In this time I made many trials to use this FUNCTION, all without success, so that is 100 % Clear, that this don’t work more.
THE QUESTIONS is : THE TOUCH PAD UNIT CAN BE CHANGED WITH A NEW ONE OR IT IS INTEGRATED ON THE MAIN BOARD OF THE LAPTOP, IN WHICH CASE THE REPLACEMENT ISN’T POSSIBLY ?

Thanks for a quick answer.
