How to listen to Metamask Ethereum events

Question

I am trying to listen to the 'chainChanged' event for Metamask, but the event never fires. When running the following snippet, the I get a console.log of the chainId once, but the chainChanged event never runs. What could be the issue? Thanks!

if (window.ethereum) {
    window.ethereum.send('eth_chainId')
        .then(handleChainChanged)
        .catch((err: any) => console.error(err));

    window.ethereum.on('chainChanged', handleChainChanged);

    window.ethereum.autoRefreshOnNetworkChange = false;
   ...
}

function handleChainChanged(chainId: number) {
    console.log(chainId);
}

Answer 1

Try window.ethereum.on('networkChanged', handleChainChanged)

From what I know, the new MetaMask api (which will change this command to 'chainChanged') is not yet live.
