Privacy self-report, what Customer Support relates to?

In the new form to self report privacy aspects of the app by the developer there is the section Customer support.

However it is not clear what this relates to. I would assume that it relates only when the users asks for the support inside the app.

Technically it could relate to email support and web form support, but then it would be a little strange request. Obviously that you get the email address if someone sends you an email, you can't block that even if you wanted to.

Unfortunately developer support doesn't want to provide any further information for this.

What is your opinion on this?
