Cloudflare Tunnel SSH Connection only Works via Setting ProxyCommand

I have a remote machine I can access only through a cloudflared tunnel. In my .ssh/config file I have

     User some_user_name
     IdentityFile ~/.ssh/somthing
     ProxyCommand cloudflared access ssh --hostname %h

This works when I do ssh

But when I just run the cloudflared directly, I only get the SSH server greetings

cloudflared access ssh --hostname
SSH-2.0-OpenSSH_8.2p1 Ubuntu-4ubuntu0.5

# After I press enter
Invalid SSH identification string.

The example at the bottom of this guide: shows cloudflared access ssh --hostname --id a61c032ee4510f8b7e2749ea0896cc14.access --secret 85dcb2301975e8b8e40deb6097645995aa4bed35c2badf098028652097c69eeb while mentioning The command relies on the SSH configuration file being set to proxy the connection through cloudflared. which I did.

In my case, I haven’t setup the service tokens auth yet. However, running the cloudflared for SSH should work directly. I don’t understand why it doesnt.
