You're five minutes from the call starting and you want more than a show of hands. Here's the whole path, start to finish, using material you already have.
Say what the meeting is for in a sentence. Lumavote drafts a title and a set of questions from it, so you're reviewing rather than writing from nothing. Nothing goes in front of the room until you approve it. A badly worded question stays in your review list, not on the big screen.
Put the six-digit code on screen, or hand out the QR code, or share the short link (lumavote.com/t/ plus eight characters). Nobody creates an account and nobody installs anything; they open the link on the phone already in their hand. Watch the join count instead of guessing whether the room is ready.
Reveal a question only when you want people answering it, not before. A live poll shows one question at a time, and answers post as they arrive: a word cloud, a rating scale, or typed answers, depending on how you set the question up. Keep it to one on screen so the room isn't skimming ahead.
Answers land on the big screen as they arrive: a rating scale fills in, a word cloud reshuffles, or typed replies group into a handful of themes within about ten seconds for a normal-sized room. You're reacting to what's actually happening, not what you assumed people think.
Ending the session locks it and produces a written summary automatically. Export the answers as CSV or Excel, or share the report link, public or restricted to people who sign in, your choice. Nobody has to retype what happened for the recap email.
