How can add a new chain to the WallectconnectV2-web3?

[DonJ92]

I'm testing WallectconnectV2 by demo(react-dapp-v2-with-web3js)
And I want to add a new custom chain based ethereum.
So I add chain info to below files.
https://github.com/WalletConnect/web-examples/blob/main/dapps/react-dapp-v2-with-web3js/src/chains/eip155.ts
https://github.com/WalletConnect/web-examples/blob/main/dapps/react-dapp-v2-with-web3js/src/constants/default.ts

But this example is using ChainData from caip-api and I have to add chain info to caip-api.
