I expect this will provide better results for you. As you are not limiting the plugin to a single organisation and excluding top level actions.
If you wish to handle more granular permissions notifications provide the mechanism to facilitate that using routing key.
Take a look at "Notification Message Format" in the help pages. This will explain the routing key format, in your case in particular how to handle the organisation which is the 3rd item in the routing key format. The notifications package by CDecanini is really useful and showing ways to handle and intercept blocking tasks etc.
#.#.org which will allow parsing of organisation data and therefore opening the plugin to support all orgnisations in your vCD environment, but using the routing key to keep it locked down at the same time.
