How do you add a chain to the WAGMI config at runtime?

Currently, the WAGMI config requires the chain to be passed during initialization. Is there a way to add more chains on the fly?

You can use config._internal.chains.setState. To see how it's used, you can search the repo for examples.. Keep in mind that config._internal is not covered by semver and may have breaking changes at any time without notice.
