import nuke

# 1. Define the function to launch the panel
def launch_label_studio():
    import LabelStudio
    # We use a global variable to keep the window alive
    global label_studio_panel
    try:
        label_studio_panel.close()

marten_menu.addCommand("Nuke Label Studio", "launch_label_studio()", "Alt+L")
