OpenMRS 3 + DCM4CHEE + Weasis PACS Solution

I would be interested in setting this up as well myself:

Can you please share the link to the O3 frontend module and backend module?

Is frontend maybe: palladiumkenya/esm-radiology-app

I have dcm4chee and Weasis already running and I need to know how the HL7 trigger is implemented with a openmrs plugin or just with an integration software which polls for new orders?

Thank you very much, Johannes
