I created a board "My Scrum of Scrum" that references several other projects project in (projectA, projectB, project C) and Issuetype in (Risk, Issue, Impediment). This does return only the issuetypes for each of those projects, however now each of those projects can see my board from the available boards in their project. I want to restrict them from being able to see my board "My Scrum of Scrum".
