How can I effectively block an app that has both a mobile app and a web version?

Hello everyone, my company is using a fully licensed FortiGate 100F firewall and I need to block Telegram. I've searched in FortiGuard and classified it as Collaboration. Now, to effectively block it and optimize my firewall's performance, should I block it via Application Control or Web Filtering? What Inspection Mode should I set? Flow or Proxy Based?

Hi FortiUser

You can block it with app ctrl, flow mode or proxy mode, and it doesn’t need deep inspection.

Hope it helps.
