python SDK - Create file requests

I would like to create a file request through the python API. I am however puzzled as to how to do that. Should I use the class EventCategory? Reading the documentation I dint understand what to put to the parameters 'tag' and 'value'.  Or maybe teh EvenDetail using this method:

dropbox.team_log.EventDetails(tag=?, value=?).file_request_change_folder_details(val=?) 

But once again, I fail at guessing the expected and available tags and values.

Any hint?

Thanks for your time!
