I have a confluence Space linked to a Jira Service Desk projet.
First of all, we don't want the Create Buttom to show up.
When a Jira Service Desk portal user only (we call it a customer) browes this specific confluence space, it allows the customer to Create a page.

As you can see, the users isn't logged, a warning shows up, and the anonymous user create a new page.




Those are the project's permission settings. If I disable the "All view" on anonymous access my link to confluence space while customers are typing will not work.
