Enabling external systems for webhooks in TypeScript Functions v2

To use a webhook with TypeScript Functions v1, you enable external systems in functions.json, as described here.

How does that work in TypeScript Functions v2? There isn’t an equivalent file functions-typescript/functions.json, to add "enableExternalSystems": true to.

There is currently no support for interacting with external systems in TypeScript V2 Functions. This is something that is being worked on and will be available before TypeScript V2 Functions move to GA.
