Thanks @BlockmanCodes The stuff you produce really helps all the web3 devs, please keep up the great work.

One question on this example -- would we be better off using the WebSocket Provider of JsonRPC in this case?

help answer, no need because this only listens for events from the latest block and in my opinion there is no significant change if you use websocket instead of http

Thank you @BlockmanCodes!
