How to get operationid in a http triggered isolated function?

[Cheng811]

Previously we use Activity.Current.RootId to get operationid for request&dependency telemetry of application insights. In isolated function, the Activity.Current.RootId is null as mentioned in the issue. So is there some other way for user to get the operationid?

An update was posted last week in the issue you linked - please use that thread for questions/updates related to Activity.Current.RootId. Closing in favor of #914.
