Programmable Action button on Dock?

I’ve got my remote mostly set up and functioning. I read on the UC site that the dock button is programmable. As of now I think I must have done something since the button is not responsive. Does anyone know how to restore function to the dock button, or how it’s programmable?

Look at the footnotes on UCs website:

Button configuration will be available via a free software update.

Kenny thanks so much. I did miss that
