I am working on a UiPath app. I would like to trigger the process on click of a button, Though I have added the process to the app and, also used out arguments from the process, I couldn’t see it while trying to add in the start process rule.
As you said when you add the process you also have some arguments with it. It should be visible when you add the process. Check if you are adding the process correctly or not.
Try to remove the process from App
Try to re-add it back in your app
Try to add a new StartProcess and try to observe if you can see the new added process.
