Here you can add the absences to be included in an absence group. If the group is defined as Manager team type, only selection of the absence will be possible. The ESS options (related to authorization scheme, file requested for the authorization, option to self add absence for trusted employees and option to use the absence in the request) are available only for groups defined as Absence request group available for ESS license.
Notice that only absences already defined in the group appear by default in edit mode. Select Show all from the drop-down, list if you want to see all absences, or Show unchecked, if you want to see only the absences not used yet with the group.
