WireGuard Peer Address Configuration Allowed IPs, IPv6?

[PFgate]

Trying to configure WireGuard so peers get IPv6 addresses. With the info below, what do I put in the Allowed IP fields of the peers in pfSense? What's the best way to test?

LAN
2600:2b01:8a3e:7a11:222:3333:4444:5555

Subnet Prefix Delegation
2600:2b01:8a3e:7e11::/64

PD
64
