Command to run from terminal to split view windows left/right

Hi, I have seen in this this post that it is possible to run commands in the terminal to change workspaces:

dbus-send --session --type=method_call --dest=org.gnome.Shell /org/gnome/Shell org.gnome.Shell.Eval string:‘global.workspace_manager.get_active_workspace().get_neighbor(Meta.MotionDirection.DOWN).activate(global.get_current_time());’

Even so, Iḿ having a hard time to figure out the analogue command in order do window split view left/right.

Any help would be much appreciated!

Mutter doesn’t export meta_window_tile(), so you cannot use it from gnome-shell’s javascript code.
