Unable to set the fetch agent

[PhilHannent]

Steps to Reproduce

To make use of socket reuse via HTTP keep alive's , we have been setting the agent on our fetch requests and using the library to help:

https://www.npmjs.com/package/agentkeepalive

As per this documentation recommendation:
https://docs.microsoft.com/en-us/azure/app-service/troubleshoot-intermittent-outbound-connection-errors#avoiding-the-problem

Observed Behaviour

The typescript compiler is complaining that:

Argument of type '{ agent: HttpAgents; }' is not assignable to parameter of type 'OmitStrict<RequestInit, "method">'. Object literal may only specify known properties, and 'agent' does not exist in type 'OmitStrict<RequestInit, "method">'

Expected Behaviour

The getPhotos and photos.get accept and use the agent parameter.

How do you do this when you use fetch? The functions exported by this package just forward the options through to fetch.

The agent property doesn't seem to exist when we use fetch:

fetch('https://httpbin.org/get', { agent: {} })
