How do I delete Custom Extensions from the Extension Market Place

[HoloWorldUK]

Hi.

First off, thanks for creating such a great platform and system.

I am trying to delete several custom extensions that I have created from the Extension Market Place but I seem to be unable to do so. I can remove without issue from an application but I do not seem to be able to delete them globally and the CLI doesnt seem to have a method for this either. Please can someone help

Thanks

Jamie
