How to get the latest lvgl (master branch) into an ESP32-IDF example project?

I created an example from the Vscode ESP-32 plugin->Show Examples->spi_lcd_touch.
The project is built and I can run the example demo.

My questions:

  • what lvgl version do I have with this example?
  • Where can I see which version this is?
  • How do I get the latest lvgl installed into this example?

EDIT: the Cmake build says lvgl/lvgl (8.3.11)
