You need to run a technical workflow to see the app in ACS. It should be scheduled to run every 15 minutes but the workflow may not be started.Workflow is called syncWithLaunchAfter that, if you can't see the app in the dropdown when creating a push it's because you need at least one application certificate/token in the app config.

Yes, that should be all that is needed.

Hello parvesh,Sorry for commenting with another question, but I'm having the same issue and you mentioned we can manually send requests to campaign.Can I register the fcm token corresponding to an ECID in campaign standard via a postman request? What would be the endpoint and parameters necessary?Thanks in advance!
