Cannot find and edit my raspberry pi kodi userdata

Running the latest version of retropie with Kodi 17.1

I am trying to use a MySQL database to centralise my Kodi media libraries and make it accessible from more than one Kodi device. I’ve found a good how to but I’m having trouble finding my user data folder for Kodi

I think I know where it’s located but I’m hitting a permission error accessing the folder via winSCP. Any idea on how to circumvent this?
