Added header div missing from responsive

I am using v9.3.2 and added an extra site header logo Div to the header. It works fine in desktop but when viewed in responsive the added div is missing. It appears the responsive output is generated by code but i cant figure out where. I think i need to add the div somewhere so it shows in responsive.

Can anyone point me in the right direction

So I manged to find it.

The div has to be added the /application/themes/elements/header-(number).php and the /application/blocks/autonav/templates/responsive_header_navigation/view.php to add the php which creates the additional div for both desktop & mobile/tablet rendering
