How to make an icon display a button state

i’m relatively new in creating UI using squareline studio. I have a Waveshare ESP32-S3 Touch LCD 7inch Display. I’m trying to make a project that displays the data received from the arduino. Also, any suggestions as to what icon is best to use?

What data do you want to display? Be more specific or sketch (digitally or on paper) how your UI should look, and we can go forward from that :wink:
