Once they are logged in, the admin of the workspace will need to go back to the page (User settings< manage member access).
They will then decide how they would like the user to view workspaces. If they would like them to be an admin and view all connected profiles, they will be automatically assigned admin privilege's when invited by an admin.
If they would only like to view their own account, the admin may click the three dots next to their name and click revoke admin privileges to make them a member.
From there, the admin can click the three dots and click "manage LinkedIn account access."
The admin can then assign the user the accounts they would like the user to have access to and click save.
