Experimental feature

"This is an experimental feature that may be subject to change in the future. It offers researchers the ability to ask a participant to return a submission. The return reason must be provided in the request and can be any free text string. The Prolific UI allows users to select any of the following options:

• Didn’t finish the study
• Encountered technical problems
• Withdrew consent
• Other ( uses the free text input)

This constructs a message around the reasons provided so there is no need to provide additional text beyond the reasons."
