[Resolved] image logo next to burger for slideout primary navigation

hi, a while back i found some nice instructions to make a slideout navigation for my primary nav. i implemented it and it works great, and you guys helped me get the site title looking right, but now we’d like to use an image next to the hamburger — only on the main page (and enlarge the burger a bit). how would i do that? i tried this code from a support thread, but had no luck.

add_action( 'generate_inside_slideout_navigation', function() {
    ?>
        <div class="off-canvas-logo">
            <a href="/"><img src="/wp-content/uploads/2020/10/CAsign.jpg" alt="" /></a>
        </div>
    <?php
} );

fair warning, the logo is larger than necessary at the momment.
