I have different projects in Jira Service Desk.
It seems that the portal is the same for the different projects. And, anyone that access to the portal is able to choose any of the projects and create a ticket on any of the projects.
I would like to have different portals. One for each project. Because I want to avoid customers that belong to an specific service (project) from seeing and, even more, entering tickets for another service (project)
As we will have different teams for each project, it's the same for Team members accessing only the project that they're assigned to.
