|

* @param {number} [opts.timeout=10 minutes] - The maximum amount of time (in milliseconds) the client will wait for a response before timing out.
|

* @param {MergedRequestInit} [opts.fetchOptions] - Additional `RequestInit` options to be passed to `fetch` calls.
|

* @param {Fetch} [opts.fetch] - Specify a custom `fetch` function implementation.
|

* @param {number} [opts.maxRetries=2] - The maximum number of times the client will retry a request.

* @param {HeadersLike} opts.defaultHeaders - Default headers to include with every request to the API.

|
||||
* @param {boolean} [opts.dangerouslyAllowBrowser=false] - By default, client-side use of this library is not allowed, as it risks exposing your secret API credentials to attackers.
