What steps are required to allow a new/additional colleague to use existing licenses?

Licenses can be assigned to groups (open the Licenses page on pCon.login and click on the pencil symbol in the table row of the license. Select the groups on the side that opens and click Save. When inviting a new member, you also specify the user groups to which he or she will belong. The colleague automatically uses the licenses assigned to these user groups. Without assigning licenses to groups, all licenses are automatically assigned to the Standard Users group. The users assigned to this group (normally all members) can then use all licenses of your organization.
