Go to Administration, then User Profiles.
Choose the profile you want to edit permissions for, or you can also create a new custom profile. For demonstration purposes, I’ll use the "Employee" profile as an example.
Within the profile, you can select the modules you want to modify. In the example below, I selected the "Goals" module and, under "Has access to the goals module?", I selected the "No" option. As a result, when a user logs into Ploomes, the goals module will not appear for them.
There are various combinations of permissions available, and you can use whatever is most convenient for your team.
