To me this sounds like the perfect use-case for a 'Wait' intermediate event:
- once the user invoked the ABC api the element can poll at your pre-defined intervall : https://developer.axonivy.com/doc/latest/PublicAPI/ch/ivyteam/ivy/process/intermediateevent/IProcessIntermediateEventBeanRuntime.html#setPollTimeInterval-long-
- after the 'Wait' event was received you can continue with a normal task (either signaled or standard)standard)
I know the samples and API is dated: but for instance the `ch.ivyteam.ivy.process.intermediateevent.beans.FileIntermediateEventBean` contains a sample...
