How to include/exclude an end-user in classic and next-gen projects?

[Functioneelbeheer]

All our (new) users seem to have default acces to all projects (next-gen and classic projects) on our site. How can I change these settings as an site admin? 

How can I create a new default rol/group where all users only have acces to a project (classic and next gen) where they're actually working on/ or are invited by a project admin?

And where can I see what permissions are set on groups? In our case: all new user are put in group: jira-users. But where is an overview of all the links of what schemes these group is connected to?

Hi @Functioneelbeheer ,

Permissions to Projects are handled by the Permission Scheme attached to the project. Specifically, it is the Browse Project permission. You can control who sees the project by modifying the Permission Scheme.
