Modify JIRA application list for particular user

[Dimitrios Danampasis]

As you can see in the screenshot below, there is a user with only JIRA Software in the Application list. 

The user has access to the Service Desk too.

So, I am trying to understand:

Where can I configure this? and  

Why does she only see JIRA Software while other users have both JIRA Software and Service Desk. What jira-thingy is determining that? Is it the group membership of the user?

We are running JIRA Software v7.8 and Service Desk v3.11

Many thanks in advance,

Dimitris

Go to "manage applications" to see who has access to each application (it's done by group)

Thanks, I verify this is based on group memberships.
