What's the standard way of adding chains?

UseDapp provides a limited set of supported chains. However I can’t seem to be able to configure it to work with alternative chains: is it a design choice or do I miss the “right” way of doing it?

Currently, the only way I see is to fork the repo and add manually the chain data in the constants folder.

Here is my (unfortunate) setup for arbitrum:

const config = {
  readOnlyChainId: 42220,
  supportedChains: [42220],
  multicallAddresses: {
    42220: '0xCe129333458f037867C81DFbD70E4D57A3b1c5eb',
}, 
  readOnlyUrls: {
    42161: 'https://arb-mainnet.g.alchemy.com/v2/API-KEY',
  },
}

While the DApp can connect to Metamask, it is unable to load the provider it appears as “undefined”.

If there’s no good way to do it, I guess adding support to manage it in the config should solve a good amount of issues, past, present and future.
