Is there Autocompletion for Thonny 4 available with LVGL 9 Micropython or LVGL 9 class/lib documentation for uP?

It is hard to know the syntax of lvgl objects in micropython, since documentation seems only to describe C syntax which is not compatible. So it ends up in trial and error. Autocompletion would be a help, even better a clear LVGL 9 class description like for micropython itself. I know there are a lot of examples posted, but who has time to find out what can be found in a class description much easier?
