Cloudflare Tunnel access

I successfully access a Cloudflare TCP tunnel as client in my openwrt router using this command:
cloudflared access tcp --hostname SUB.DOMAIN.COM --url 127.0.0.1:8087
Kindly note I don't want remote access to openwrt, I want to access a tunnel FROM openwrt.
How can I make this permanent?

Clone wg parameters from a virtual machine with cf client?
