How to make .../bases/xxx request? e.g. List webhooks

[lishenwp]

There seems no way I can make a webhook request? Even with Base.makeRequest I could only start from the basic url https://api.airtable.com/v0/{baseId}... which is hard coded.
Unless I replace the {baseId} with 'bases/{baseId}' which means I need multiple client instances for different set of APIs.

Or am I missing something?
