This problem is pretty common. I am not that good with all these technicalities. But as a solution to this problem, I had my Freshdesk and Slack integrated using this no-code automation platform, Automate.io. I get instant notifications for all Freshdesk comments in my Slack channel. I think using these integration platforms are an easy fix for problems like these. You can try this app or other similar apps like IFTTT or Tray.io who offer similar services.
