2.13" e-ink Display Raspberry Pi v3

Looking for troubleshooting steps I can take to get this device working. Not a programmer, just learning. The example scripts are not working for me. Working on a Raspberry Pi Zero W with a fresh install of Raspberry Pi OS Lite 32-bit, updated, with SPI and I2C enabled. Thanks for any help in advance.
