In which directory do I find a specific HTML code of my wordpress page? Some of it seems to be missing after checking all pages [closed]

So I would like to access this part of the HTML and be able to edit it (see image below)

However when I access my ftp server and navigate to the Footer.php section, this part of the HTML is not to be found. I also checked Header.php and all other files in the wp-content/themes/mytheme but to no avail. Refer to image below. So where can I locate ‘menu-image-title’ please? Thanks in advance.

The code you are referring to is a menu, and in your screenshot, is likely to be the line starting wp_nav_menu…

Look in your WP admin under Appearance > Menus, and you should have a Social Media Links menu it seems…
