The solution is this:
- François and Serge need Nextcloud accounts. I created them, using the same email accounts they use for Edgeryders.
- These accounts are assigned to a group of users called “Architects” (not really necessary, but more elegant). They are not part of the Reeflings group.
- I created a folder called “Stekke and Fraas folder” within the Team Building folder
- I shared that folder with the Architects group.
This should give François and Serge access to that folder and any sub-folder we may create, but not to the superfolder (Team Building).
