LCD I2C not working

[Wickfut]

Are there any instructions on fitting a 20 x 4 I2C LCD display?

I've never had a problem using these displays with an ESP32, but I cannot get it to work via the I2C extender port on the KC868-A8M

TIA

what problem details?

The display displays nothing!

Is there any example code available?

I'd be surprised if I were the only person to do this...
