communication esp32-s3

I have the CrowPanel ESP32 HMI 7.0-inch Display. I would like to have the screen communicate with an ESP32-S3 via UART; the ESP32-S3 needs to be able to communicate with the display and vice versa. does someone know how to do this, I tried to communicate with an arduino uno and it works fine, once i try it to communicate with an esp32 it just doesn't work. can someone give me extra information or a sample code? thank you
