Documentation for ClientConfig parameters?

Hi,
There are multiple parameter settings for the ClientConfig,
https://github.com/apache/pulsar-client-node/blob/d2c0d1e374f8e9f25934bd679436da0872b6bc8e/index.d.ts#L25-L33

Is the documentation for these parameters available somewhere? Ideally I'd suggest adding some comments directly in the typescript definition, so users of the library can see some documentation while developing.

Start by inspecting the ClientConfig parameter declarations in index.d.ts at lines 25-33 and check whether documentation exists elsewhere in the repository. Document the parameters in the TypeScript definition, or identify the existing documentation location, and verify that users can find the parameter descriptions while developing.
