Wildcard for networking.firewall.trustedInterfaces

What is the wildcard for networking.firewall.trustedInterfaces? The container documentation says it should be networking.nat.internalInterfaces = [ "ve-+" ].

According to the nftables documentation: “Like with iptables, wildcard matching on interface name prefixes is available for iifname and oifname matches by appending an asterisk (*) character.”

Is the documentation in error? What is the proper wildcard character?
