Using the QuickTask Template (Love it😁) provided I have tweaked a couple of things. I am collecting Planner plans by Teams Group as values but need a pre-existing row to be added to the beginning of the collection.
Below is what I have:
ClearCollect(MyGroupandPlansGalleryItems, {groupname: "NotAGroup2", id: "NotAPlan2", title: "Create New Plan"});
Collect(MyGroupandPlansGalleryItems,If(!IsEmpty(MicrosoftTeams.GetAllTeams().value),ForAll(MicrosoftTeams.GetAllTeams().value, AddColumns(Planner.ListGroupPlans(id).value,"groupname",displayName))));
Clear(MyPlansGalleryItems);
ForAll(MyGroupandPlansGalleryItems,Collect(MyPlansGalleryItems,Value));
Which gathers the information correctly.
Problem is I just want to add the values after the pre-populated collection and not just the values. (Where the red arrow is below).
