IPSec-VPN Dual Stack IPv4 and IPv6

Hello, for the dial-in via IPSec VPN we now have to create the possibility that this can also be done via IPv6. Our internet provider is already IPv6 capable. The only thing missing is the configuration on the FortiGate (interface) and the VPN configuration. My question is whether it is possible to extend the existing VPN configuration for the FortiClient for IPv6 or does an additional configuration have to be created?

We're using FortiGate 6.0.
