What overlay is compatible with the Raspberry Pi CM5 to use the DFR0550_v2 5" Touchscreen

I have spent hours trying to get the   DFR0550_V2 5" touchscreen working with a new Raspberry Pi CM5 using the official RPi CM5 IO board. 

Is it actually compatible and if so, what overlay can be used to make it work. So far nothing has worked, the generic overlay detects it but doesn't display anything.

We're currently prototyping but we're hoping to order a batch of 50 if suitable, can anyone help?

Thanks is in advance
