Route48 WireGuard tunnel

[pinguin]

Hi all!

New to opnsense but recently setup an s920 and looking to run v6 assignments through an r48 v6 tunnel which i used to do when i was running openwrt solely on an AP, however i used to achieve this through standard WG conf and IPv6-PD but now i can't seem to set the same thing up using opnsense, anyone have any experience with this as i can't seem to find any steps online regarding this

Thanks! :)
