Edit
My mistake is not calling the off-canvas-bar
I'm still learning how to make changes using actions and filters.
How would I call the
Off-canvas-bar
That's the challenge.

You can use this code to get the menu button
<a href="#offcanvas_menu" class="uk-button" data-uk-offcanvas="" data-markup-id="beans_primary_menu_offcanvas_button"><i class="uk-icon-navicon uk-margin-small-right" data-markup-id="beans_primary_menu_offcanvas_button_icon"></i><!-- open output: beans_offcanvas_menu_button -->Menu<!-- close output: beans_offcanvas_menu_button --></a>
iether use it inside function or in you own header function if you have ur own header funtion
