Delete a Report Element
You can delete a report element using the DELETE method on the report-elements endpoint. You need a token with write privileges, otherwise a 401 or 403 will be sent back.
Selecting a report element to delete is done with the same parameters as the GET endpoint.
In order to avoid massive deletions by mistake, you can only delete one report element at a time.
