Installing Tailscale on an ASUSwrt-Merlin router

Hello, I’d like to connect all devices in my house to Tailscale via an ASUS router running Merlin. Is that possible? I saw there’s an Merlin opkg called tailscale, but installing that just results in “Illegal action” for any command I can think of (i.e. tailscale up). There doesn’t seem to be much (any?) documentation on this. I see that Tailscale is running on OpenWrt so I’m hoping it’s possible on Merlin as well.
