How do I add a description above Logo in WordPress Customizer?

Question

I need to add a custom description above the Site Identity -> Logo section in the WordPress Customizer, for example "Use an image that is 250px by 250px."

(Image attached for more details)

My first thought was to look through this documentation: https://codex.wordpress.org/Theme_Customization_API which I've used to add new controls,but since the logo already exists, it seems a bit different.

Do I need to hook into it somehow?

Any help would be appreciated. Here's an example of where I'd like to add the description

Update. The solution that worked for me was to override the logo. So for example:

$wp_customize->add_control(
    new WP_Customize_Image_Control(
        $wp_customize,
        'custom_logo',
        array(
            'description' => esc_html__( 'Use an image that is 250px by 250px.', 'namespace' ),
            'label'       => esc_html__( 'Primary Logo', 'namespace' ),
            'section'     => 'title_tagline',
            'priority'    => 8,
        )
    )
);
