Custom menu including also primary menu items

by

In my function:

    register_nav_menus(
        array(
            'menu-1' => esc_html__( 'Primary', 'mySite' ),
            'menu-2' => esc_html__( 'Secondary Menu', 'mySite' ),

        )
    );

And then in my header to display the menu:

<?php
wp_nav_menu(
array(
'theme_location' => 'menu-1',
'menu_id'        => 'primary-menu',
)
);
?>
