Adding a text slider to secondary navigation menu

Hi!

I want a rotating text slider to on my secondary navigation area to display site wide news.I'm using this plugin called text slider to do this. https://wordpress.org/plugins/text-slider/

The problem is I don't know how to integrate this plugin to the secondary navigation area. There's a code <?php text_slider(); ?> that allows to integrate this to the theme.

I'm using divi theme by the way.

Thanks
