Trying To Add a Custom Control to the Customizer

Hello guys!

i am trying to add a custom control to my customizer. The idea is to only have a description with a link, so there are no real controls.

The section needs a control for it to show, so I need to create my custom control type in which only the description is shown.

I have the following code in a mu-plugin, but it is not working properly. Could you please point me in the right direction?

// Function to add the "Request a Site" link
function weebir_add_section($wp_customize) {
   $wp_customize->add_section('weebir_request_site', array(
    'title'      => 'Solicita un Sitio Web',
    'priority'   => 0,
    'description'=> 'Description and link here',

        'default' => 'Default copyright text',

    $wp_customize->add_control(	'weebir_seleccionalo', 	array(
		'label'    => 'Seleccionalo',
		'section'  => 'weebir_request_site',
		'description' => 'Esta es mi descripción',
        'type' => 'requestsite',

    if( class_exists( 'WP_Customize_Control' ) ):
	class WP_Customize_Textarea_Control extends WP_Customize_Control {
		public $type = 'requestsite';

		public function render_content() {
			<span class="customize-control-title"><?php echo esc_html( $this->label ); ?></span>
			<textarea rows="5" style="width:100%;" <?php $this->link(); ?>><?php echo esc_textarea( $this->value() ); ?></textarea>

add_action( 'customize_register', 'weebir_add_section' );

Thank you!
