I'd like to ask a small group of people feedback on my mentorship program. They can give anonymous feedback if they choose to. I can use Typeform for this but it's a small group so I'm wondering if there's any Slack extensions that can do this :)
Speedback is built for anonymous peer reviews in Slack, which might work for your needs.
Alternatively, you could create a simple Typeform form to poll and ask questions of your group but it won't be integrated in the way you're describing.
