Response from repository_dispatch

I am sending post request using repository_dispatch as documented in

In my case, multiple users will be running the workflow by sending request from postman.
What I am trying to figure out is how can I get hold of the job that got triggered when there are multiple jobs getting triggered by multiple users hitting the same post endpoint.

Currently i get 204: no-content as the response without any information of the actual job that was triggered.

How can I get hold of the job and possibly return the url of the job in response to the post request in addition to 204: no-content?
