Get user info (roles, ...) in a plugin


I am developing a plugin displaying a list of items. Some of these items needs to be highlighted if created by a certain team.
My idea is to attribute a specific role to the members of the team to distinguish them from other users, so I need to be able to check the roles of the active users when a new item is created.

Is there a way to retrieve this kind of information from the server-side or the client-side?
I tried server-side but adding opendistro_security to the dependencies of my plugin prevents it to start.

We are using the version of the OpenDistro plugins and the plugin I am working on uses the new plugin platform.

Thank you!

Could someone help me with this please?
