GenAI: Automatically display required fields from the Test Screen in the GenAI creation window

Currently, when using the GenAI Test Case Generation feature, users cannot see which fields are required at the time of creating a Test. This can lead to missing information and validation errors later on.

It would be very useful if GenAI could automatically identify and display the required fields defined in the Test Screen configuration, allowing users to fill them in directly within the GenAI creation window.
