Can't CIDR For Split Tunnling

Hi,

I want to add CIDR for split tunnling, I can add my address using old command warp-cli add-excluded-route 172.16.13.0/24 but can’t add using new command warp-cli tunnel ip add 172.16.13.0/24 and will get:
error: invalid value '172.16.13.0/24' for '<ADDRESS>': invalid IP address syntax

While clearly in description of tunnel command it describe ip command for “Configure split tunnel IP ranges” not single IP.

Thanks
