Connect to SSH server with Short-lived cert via WARP

I have already set up my server with a Cloudflare CA certificate, so now I can log in to my server using cloudflared.

On my client computer, I have both WARP and cloudflared installed. I want to use a single app to access all my resources. In the official documentation https://developers.cloudflare.com/cloudflare-one/identity/users/short-lived-certificates, I can learn how to set up the client’s SSH configuration to connect to an SSH server. However, the documentation only provides the cf_key file location for the cloudflared use case. How can I set up my configuration with the WARP client?
