Play animated GIF in CircuitPython 8.1.0 Beta 0, run on ESP32-S3, display on ST7789 SPI TFT.

In CircuitPython 8.1.0 Beta 0, animated GIF is supported with gifio.OnDiskGif.
~ ref: Release Notes for 8.1.0-beta.0

It's a exercise to play GIFs running on Espressif ESP32-S3-DevKitC-1 (flashed with CircuitPython 8.1.0-beta.0), display on 1.14" 135x240 (RGB) IPS ST7789V SPI.

To setup library and connection, refer to last post ESP32-S3/CircuitPython 8 display on ST7789 SPI TFT.
