Forge Deploy and Forge Tunnel

I’m connecting jira and slack by using forge app.
I’d like to send a message and GIF file to slack when an issue is done.
My app works when running forge tunnel command but when only running forge deploy, only the message is sent.
How should I improve my app?

are you whitelisting the slack API in egress permissions?

The manifest.yml file is like below.

permissions:
  scopes:
    - read:jira-work
    - write:jira-work
    - read:jira-user
  external:
    fetch:
      backend:
        - slack.com
        - {Incoming Webhook URL}

Is it not enough?
