In Service Bus' TypeScript samples we are importing https-proxy-agent, however: There are no TypeScript definitions for this package. This issue even exists in the source repository for this module, see: TooTallNate/proxy-agents#27

As @ramya-rao-a suggested offline:

Contributing the typings upstream is the right step forward.

Let's get in touch with @TooTallNate and then let's send him a PR with the missing definitions ✨

Note: I have assigned this to me, but feel free to assign it to someone else.
