SSH Agent forwarding

Can I use my derived ssh key for on a remote server?
Can I do it using SSH Agent Forwarding or is that not an option right now?

Yes, you would use the OnlyKey Agent for this - OnlyKey SSH/GPG agent | Docs

Thank you I figured out how to do this.
However, the Onlykey docs are not clear on how to do this.

I followed these instructions trezor-agent/ at master · romanz/trezor-agent · GitHub to figure it out.
