I am using the npm package [@microsoft/applicationinsights-web](https://www.npmjs.com/package/@microsoft/applicationinsights-web) in an Angular application.

I have custom headers in my http service which are overriding the correlation headers ('Request-Id' and 'Request-Context'). I looked through the appInsights object, however was unable to locate these two properties to appended them to my custom headers. Does anyone know how to get a handle on these programatically?

app insights config

```js
private appInsights = new ApplicationInsights({
    config: {
        instrumentationKey: environment.ApplicationInsightsInstrumentationKey
    }
});

this.appInsights.loadAppInsights();

```

http call

```js
getHttpOptions() {
    return {
        headers: new HttpHeaders({
            'Cache-Control': 'no-cache',
            'Pragma': 'no-cache',
            'Content-Type': 'application/json',
            Authorization: `Bearer ${this.authService.authToken}`,
        })
    };
}

getDetails(): any {
    let detailsUrl = `${this.apiBaseUrl}${Details}`;
    return this._httpClientService.post<any>(detailsUrl, this.getHttpOptions()).pipe(
        catchError((e: any) => this.handleError(e, this)));
}

```
