Amend description of menu locations in customizer? I just want to add note that I have limited menu depth. Not really sure how to do it.
I refer to this description under 'Menu Locations'
Your theme supports 2 menus. Select which menu appears in each location. You can also place menus in widget areas with the “Custom Menu” widget.
or to add description for Menu panel.
I tried like this
$wp_customize->get_setting( 'nav_menus', array( 'description' => esc_html__( 'new description', 'theme_name' ), ) );
