In Jira Service desk I have created 2 projects. ProjectA and projectB, in projectA I have created users test1, test2, test3, and another project namely projectB in that I have created users test4, test5, test6,. When I am loging in Jira service desk with test1 user I can see both project projectA and projectB, I want to restrict that user test1 should see only his project so, that he can raise any tickets in his project only.
I have done some permission staff as well, but still facing the same problem.
This is my test1 user view, he can see rest projects as well,

This is my permission scheme

This is my Global permissions

Please let me know where I am wrong or missing with some permissions.
Thank you,
Mohd Zakir.
