FortiGate to AWS VPN with link monitor

Afternoon!

Im very new to Fortinet and trying to get a VPN between my site and AWS using the dual VPN gateway config.

AWS provides a config file for both GUI and CLI but its from a long time ago and the commands are not compatible with V6.

Has anyone else managed to get the link-monitor working with the dual routes?

Im surprised this isnt a common guide on the Fortinet site but cant really find anything?

Any help would be greatly appreciated!
