WYSWIYG field - Render Contact Form 7 Shortcode on Front End

Hi Guys

I have created "WYSWIYG Editor" custom field. I have placed a contact form 7 shortcode in my WYSWIYG custom field but the contact form is not rendered, only the shortcode [contact-form-7 ..... ].

I have tried to use a function in my functions.php but I'm not sure I got it right.

function render_shortcode() {
$text = rwmb_meta( 'my WYSWIYG ID' );
echo do_shortcode( wpautop( $text ) );
}

Sincerely
