Arduino Giga Display Shield - LVGL Multitouch support

Hi,
I’m currently working with the following setup:

I am using the Arduino_H7_Video library to enable LVGL on Arduino Giga R1 with the Giga Display Shield. The library is based on LVGL v8.3.x, which currently supports only single-touch.
I am interested in implementing multiple touch support. Could you please guide me on how to achieve this?

Thanks.
