I don't think you can.  The plugin itself needs to check in run() if a
worker is needed and schedule a worker thread if so.

I am not aware of a mechanism to specify custom available URI messages
to be used in generic UIs.

Can you make the decision if to launch a worker dependent on some
internal state rather than a message?

The message from your custom UI should just modify the internal state,
as would interaction with the generic host-UI. -> both will eventually
trigger the worker.
