The GroupMember table serves to establish and manage the association between users and their respective groups within the Group package. Each entry in this table represents a unique membership instance, containing fields that specify the group ID, member ID, role or permissions assigned to the member within the group, and timestamps for membership creation and updates. This table facilitates collaborative interactions and access control settings, ensuring that members can engage in group activities and share resources effectively while maintaining clear records of member roles and status within various groups.
