Hi @RJ1207
I think you need to have a "Watch events" module to watch for new tasks that satisfy your criteria (convertedOpTaskName is not blank).
Then a "Search" module to search for the request (convertedOpTaskName) and get its projectID. If the Project ID is the same as your request queue's project ID then pass let it pass through to the next module
In this next module you subscribe the user to the project using a custom webhook module. I'm not sure how to structure that but can help you with this link - https://experienceleague.adobe.com/en/docs/workfront-fusion/using/references/apps-and-their-modules/....
Hope this helps. Happy to chat through in case you run into any roadblocks
