How to publish a BonitaSoft process?

I developed a simple process in the BonitaSoft Community 7.3.3 tool, how do I publish this process for other users to access it?

Aligning organisation between portal and studio

How do I get changes made to the organization (eg: adding a group) via the admin portal to show up in the studio so that I can configure actors to use the groups?

I understand that you have to "publish" to go the other way (studio -> portal) but cant find the portal -> studio mapping.
