M5StickC Plus wiht RoverC Proc & Joy C

Hi Looking for a quote to supply some simple Arduino code to provide functionality for the following:
M5Stick C Plus unit is to be used in conjunction with RoverC pro hat and JoyC hat. The Rover Pro comes equipped with a simple servo driven claw/gripper. I would like to be able to operate the gripper using the JoyC handset. Strangely/disappointingly M5Stack do not supply code to operate the RoverC pro and the JoyC. Whilst I have found an example of such code on Github I can not get it to work.

Please see the below links for the hardware to be used:

Please see the below example of what I want to achieve :

I hope someone can help.
Many thanks, Will Lockwood
