How can we trigger transport handler in publisher when any pages are replicated.

We have created our custom akamai flush agent, which should het triggered when we publish any page

http://localhost:4503/etc/replication/agents.publish/akamai-flush-agent.html

Test connection of akamai flush agent is successful but it is not getting triggered when we publish any page from author to publish instance.

Use Case - we need to get the page path in AkamaiTransportHandler.java in publisher instance which is getting replicated from author. 

We have followed the documentation given in this https://aem.design/blog/2021/04/25/creating-akamai-flush-agent.
