How to pass body through `httpclient` delete request in Angular5

Question

How to pass body through httpClient in delete request?

Please check my code. Is there any idea to pass data through body in delete request. There is no proper source how to call this request in angular 5.

let body = removeFile;
    return this.httpClient.delete(`${apiRoot}RemoveQueryData`, {
      headers: new HttpHeaders().set('Content-Type', 'application/json').set('Authorization', `Bearer ${accessToken}`),
      observe: removeFile
    })

That body I am passing through observe. It's throwing following error.

Error:

Error: Unreachable: unhandled observe type [object Object]}
    at HttpClient.request (http.js:1520)
    at HttpClient.delete (http.js:1546)

For now Angular HttpClient doesn't support body in delete method you can post body throgh Request Options.

let body = removeFile;
let queryParams = new HttpParams().set('key', value); // key and value are both strings
let headerData = new HttpHeaders().set('Content-Type', 'application/json').set('Authorization', `Bearer ${accessToken}`);

return this.httpClient.delete(`${apiRoot}RemoveQueryData`, 

    new RequestOptions( {
      headers: headerData,  // optional
      params: queryParams,  // optional
      body: body,
      observe: 'response',  // optional
      responseType: 'response' // default type json ...
    })
   );
