Sophos XG v18 and AWS IPsec VPN

Hello,

Followed this guide to configure AWS VPN and it looks okay, however a bit confused whether to configure a second tunnel for the Tunnel 2 in AWS ?

if it has to be configured how should i route the packets ? As of now packets are statically routed via xfrm1 interface.
