FUOTA - How to cancel or delete a firmware job?

Hi,
I am using firmware update mechanism in the chirpstack application server.

I want to delete FOTA requests for certain devices as they are not going through. I looked for an API and there is only APIs for Create and List, Status available currently, but there is no API to delete an active job.

Is there any quick way to accomplish this?

Any help would be appreciated,

Thanks,
