New App in PSU Desktop showing submit form

Product: PowerShell Universal Desktop
Version: 4.1.7

Installed PSU Desktop. Created a app.
When opens the app it show a form before entering the app.
What is that? How to get rid of it?

Do you have a New-UDForm call in your app? If so, have you defined OnSubmit? I ask because that will popup when not specified because it is required.
