Jira Cloud Addon - Display a dialog (web item) based on the webhook module

[Aghilan Paramasivam]

I am building a addon using Atlassian connect in Javascript.

I'm trying to display a dialog in UI based when i recieve a webhook event.

For example, when a comment is created, I wish to display a dialog on the UI. But, I'm not able to connect to the addon view from my addon backend-server.

Please help me on ways to address this. Thanks in advance
