App Insights not logging dependencies in Node.js

The documentation [here](https://docs.microsoft.com/en-us/azure/azure-functions/functions-monitoring#dependencies) states:

> Functions v2 automatically collects dependencies for HTTP requests, ServiceBus, and SQL.

However, I'm running a v2 Function App with Node.js and I'm not seeing my outgoing dependencies getting picked up automatically by Application Insights.
Is this only available for .NET? Do I need to initialize App Insights in each of my functions? The Function App is already associated with an App Insights instance, and I'm getting request logs, error traces, etc.
