$ tmux -S /tmp/tmux/shared attach -t robolab-startuptmux and screen are so-called terminal multiplexer that allows you to run multiple terminal sessions from inside a single terminal or SSH-session. The EV3 brick has a tmux session running in the background, so that if the SSH-connection fails the program you are running continues to be executed, instead of terminating it with the SSH-session.
For the Online-RoboLab, we use the Mothership server as hop with a screen session holding the tmux session.

The EV3 brick has a hidden tmux session running that you are not supposed to attach to.
Attaching to this secret session will not work with the regular commands, since you should only attach to that session via the deploy.py.
If you feel confident enough with tmux about not breaking said secret session, you can attach to it by replacing the regular tmux in the commands with the following:
$ tmux -S /tmp/tmux/shared attach -t robolab-startupFor further reading you can check out the following links:
