Using the service GetUserRecipientsOfEvent
Looking to make use of the service:
GetUserRecipientsOfEvent

I am unsure of the input's and what to populate them with.
I am expecting to get a list of users from the Test trigger that I've created.
Here is the trigger:

I've followed this guide to get the custom handler working to a point where I am able to see that the handler is triggered from logging inside the service. I am aware this this guide is for thingworx apps and I am using foundation but it does work. Working with Thingworx 9.4.4.
Now I would like to get it fully working by retrieving the list of recipients and then referencing them so that I can actually notify the users included in the recipient list.
Hoping someone here has used this service and can point me in the correct direction.
