SSH between symetrical machines using cloudflared on different zones

I have two machines running several services using Cloudflare ZeroTrust tunnels, and each machine uses its own Cloudflare Zone (DNS domain).
I need to communicate these two machines through SSH for replication purposes. I’m unsure if I can use the “Connect to SSH server with cloudflared access” method described in the Cloudflare documentation.

Can this be done?
