Best practices for a 10-minute live pitch with Google Slides integration?

Hi everyone!

I’m preparing a 10-minute presentation for a transport company to be shown at a big forum. I want to keep the audience engaged by using a live poll with real-time charts directly inside my presentation (using the Google Slides add-on).

I have two main questions:

1. What is the smoothest way to transition from a content slide to a live poll without losing the "flow"?

2. For a short 10-minute slot, is it better to place the poll in the middle to wake up the audience or at the very end for feedback?

Any tips on making the charts look "premium" to match a high-end business deck would be much appreciated!
