## Code

```php
add_action( 'after_setup_theme', function () {
    if ( current_theme_supports( 'custom-logo' ) ) {
        return;
    }

    add_theme_support( 'custom-logo', array(
        'height'      => 120,
        'width'       => 400,
        'flex-height' => true,
        'flex-width'  => true,
        'unlink-homepage-logo' => true,
    ) );
}, 20 );
```

## Notes

Your theme still needs to print the logo, for example with the_custom_logo() in header.php.
