Here are demos from the product page available for the Qualia ESP32-S3 that run in Arduino. Below is the code.
This currently will not compile with version 3.0.0 of the ESP32 Board Support Package. Please use version 2 of the BSP.

This sketch was written for either of the 2.1" Round 480x480 RGB-666 displays.
Now upload the sketch to your Qualia ESP32-S3 and make sure a round display is connected. You may need to press the Reset button to reset the microcontroller. You should now see text appear on the display like in the image below.
