Normal monitoring user

I have the checkmk connected to the ldap. While they are users with an administrator profile, they can see everything, however, when a non-administrator is logged in and their profile is as normal monitoring user, this user cannot view any equipment. What should I do to show the hosts? I have checked the normal monitoring user roles and they are by default visible. My question is Should something be set up separately or am I missing a step?

Thank you very much for your time!

The “normal monitoring user” role doe snot have the permission to see all hosts and services.

Such users only see host and services they are contact for via assigned contact group(s).
