How can I use the built-in RGB Display (GPIO26) with Scratch3

Hello,

CrowPi2 is a great device!

But please give me a hint how my son and me can program/use the RGB-matrix display under the Keyboard (GPIO26-RGB) with Scratch3?

When I use, e.g. the Scratch 3 Sense Hat Extension than only the emulated RGB-Display shows the output....

How to change that so that the output goes to the real RGB or both at the same time? Any hint is welcome!

Thanks to the Elecrow team for the great device they created!

Best regards,

Erw
