def create_script_editor_button():
    """Add a tool button to the tool bar"""

    section_name = 'Plugins'
    se_command = 'import my_module;my_module.show()'  # todo replace with your code
    label = 'My Plugin'
    tooltip = "my tooltip"

    menus = unreal.ToolMenus.get()
    level_menu_bar = menus.find_menu('LevelEditor.LevelEditorToolBar.PlayToolBar')
    level_menu_bar.add_section(section_name=section_name, label=section_name)
