Integrate with Microsoft Teams as an app
There is a strong need to be able to control the forum of people voting/comment but doing so in an anonymous way. There is no great way to do this in Microsoft Teams and the only apps available that support this are TinyPulse and other competitors. Microsoft Teams is important because it's used in enterprise scenarios and already can control access to various groups etc.
I use PollEverywhere regularly with my organization of almost 100 people. Being able to extend it's usage to garner feedback asynchronously and anonymously outside of meeting rooms and presentations would really take it to the next level.
