Feature Request: GET API for virtual background to obtain id string

Currently there are two APIs available for managing virtual background - a POST API to upload, and a DELETE API to remove an image.
However, the DELETE call requires the ID of the background to delete, and so far I can only see that this is provided if it’s uploaded via the API, and captured at the time of the request.

I woud like a GET API to be able to obtain the file IDs of the virtual backgrounds that exists, ideally with some way of identifying which they are, so that they can be removed via the API more easily without having to store the ID manually when uploaded with the POST call.
