Hi @Phylo_IF 
That report is the one that runs when you press ‘Export’ from the poll itself.
If you’d like to run it manually you can grab the post_id from the json of the post the poll is in, and the name would default to ‘poll’ if there’s only one poll in that post (if you have multiple they default to ‘poll1’, ‘poll2’, etc, though you can type a more descriptive replacement into the composer when creating them if you wish).
