Adding new member to 3D experience

Hello,

I am the team leader of a student project. We have received last year a sponsorship for SOLIDWORKS Desktop + 3DEXPERIENCE Engineer (which expires in 2027). 

Recently, out team has gained a new member but he doesn't have access to 3DExperience. How could I update the team members list so that I can invite him to the platform and add him to the workspace?

Thank you in advance!
