Power Platform Community Forum Thread Details

Hello, I'm new to Power Automate and trying to explore it's capabilities. I have a Legacy Application on my desktop (IBM iSeries). I'm starting with a simple scenario, extract a record number from an excel file and and output it to the application. Using the "Click UI element in window" action the entire interface is not being recognized. I want to input a record number into the Pro Number "text box". Power Automate is only recognizing the "Pane" object. Are some applications simply not supported by desktop flows? or is there another action that supports this use case? thanks
