Hey there -
So in On-Prem I would just use CAML Query and put the list GUID in there and query it. All I have at my disposal is the ListId, and the list coming back will be different sporadically.
Within Query List, I HAVE to name a List via hardcoded dropdown so that won't work.
Within O365 Query List, it looks like it lets me use a variable to name my list - so, cool, closer - but how do I retrieve the name of the List that correlates to my ListId?
