Can (Should) I share my project's QR code for livestream coding event?

I will have my first livestream tutorial of creating an Expo app with an interactive d3.js map using hooks.

I would like the viewers to connect to the app while developing in real-time and thus would like to share the QR Code of the app so people can see it in the Expo client app. However, I guess I will have around 100 people watching the stream and I was wondering if this would be too many concurrent users for my app while I am developing it live. Is this possible and if yes, which things I should take care of in advance to prepare?
