Map this field to WPforms Post Submission field?

I’m working on setting up WPforms Post Submission addon for user generated content, which will input data to a custom post type (event). I need to create a way for users to specify if an event is recurring, which the RRule Field plugin allows, but I need to map it to the front end form in WPforms. Has anyone done this yet? I’m not a true developer so I don’t quite know where to start.
