ssh proxyjump into tailscale network from outside network

Hello!

As in the title; is it possible to proxyjump into the tailscale network from outside the network, such as from the local library or university computer? Something like:

ssh -J user@bastion user@tailscale-ip

Or:

ssh -A -t user@bastion ssh -A -t user@tailscale-ip

Thank you kindly for the help!
