URCap Installation Node Operator Interface

Hello to all,

I am trying to develop some kind of GUI for the operator to be used for START, STOP the robot, loading a program etc.
I have designed the layout of the installation node but I cannot make it full screen or bigger that the space there.
How can I make that when I click on the URcap from the installation node that I will have a pop up maybe not exactly full screen but bigger than the actual size and from there I can press the buttons?

Thank you very much in advance!
