T-Echo with buttons and keyboard

Hallo all great people!

I’m working on adding a little navigator switch for canned messages and a detachable keyboard to the T-Echo.
Actually both work great on the little e-ink display.
But I can only add them separately in the Meshtastic app.
One will work and the other one don’t.

Anyone know a way I could get both working at the same time?

Here is a picture of the setup:
(I will update with more when I get them installed in the enclosure)
