I'm trying to build a MERN app with a web3 part, I have a typical authentication step in the beginning (centrelized), then the user will connect his wallet and send a transaction to the smart contract through the function createBid.
this is the code of the function of the smart contract:
in findwinner() there is an event that outputs the 2 winning addresses, my question is how I can notify the 2 users related to that addresses, I mean some methodes related to MERN stack and ethers.js because I'm using them for the first time and thank you!

you can listen for events in frontend, I'm assuming you're using ethers for contract interaction, ethers provide helpers for that, e.g.
I hope this may help you further https://docs.ethers.io/v5/concepts/events/
