How to access to work profile's files?

GrapheneOS user here. I’ve used shelter to create a work profile. In this profile i have sandboxed play services and what’s needed to have Gcam working. Then, my main profile is 100% google-free.
But how to access work profile’s files to backup my pictures? Is it possible from PC with cable? Or do i have to copy/transfer this folder to the main profile first and then backup from my PC with the cable?
