Wireguard, allowed-ips, ipv6 and multicast

I'm trying to use vxlan encapsulated into Wireguard tunnel, with a
multicast group for announcement.
ip -6 link add vxlan100 type vxlan id 100 dstport 4789 local
`wg0Ip6_lock` group ff05::100 dev wg0 ttl 5
All works very well when i set wg tunnel with ::/0 as allowed-ips,
but if i'm trying to be more restrictive, as ff05::/32 for example,
it does not work.
Is a specific interaction between allowed-ips and multicast group in ipv6 ?
