Invite to group with link (group code)
Group code is an alternative way of giving members access to your group.
With group code enabled, members can ask to join the group without the administrator having to add their details first. Each group is given a unique code and link that can be shared with those who should have access.
The group code feature can be enabled by the group administrator, either via the group settings (app) or via the members' tab for the relevant group (web).
Tip: If the members of your group are asking for a group code even though you have already added them as members you should check to make sure they have registered with the same contact details that you have added them to the group with.
