add_action has no effect

I’m trying to add a logo to the navigation menu.

Google led me to this snippet:

add_action('generate_inside_navigation','generate_navigation_logo');
function generate_navigation_logo()
{
?>
	<div class="site-logo">
		<a href="https://sytex.dk/"><img src="https://sytex.dk/wp-content/uploads/2018/01/logo.png" alt="" /></a>
	</div>
<?php
}

′

but when entered in Code snippet, it has no effect.

Am I doing something wrong – or is karma just a bitch?
