How can I use the ButtonGroup in AppDesigner?

Hello,

I haven't been working with the App Designer for very long and I currently have a proble. The point is that I want to create a ButtonGroup with 2 buttons. I created the callback function "ButtonGroupSelectionChanged", which creates "selectedButton = app.ButtonGroup.SelectedObject" for me. Now I would like to execute an action if button 1 is confirmed and execute a function if button 2 is confirmed.

How can I query this in the code? I am not sure what is in the variable selectedButton.

With a SwitchButton I solved it as follows (The two positions are called "active" and "inactive").

            if strcmp(status, 'inactive')
                app.Lamp_LEDoff.Color = 'red';
                writeDigitalPin(app.a, 'D11',0);
            elseif strcmp(status, 'active')
                app.Lamp_LEDoff.Color = 'green';
            end

Unfortunately, this does not work with a button.

It would be great if someone could help me!
