How to send CF to vendor email

Hello,
I have installed the multi-vendor plugin from YITH on my woocommerce installation. I have received from the development team of YITH the code below:

if ( defined( 'YITH_WPV_PREMIUM' ) && YITH_WPV_PREMIUM ) {
 function get_vendor_email() {
 $vendor = yith_get_vendor( get_post(), 'product' );
 if ( 0 < $vendor->id ) {
 return $vendor->store_email;
      }

 return '';
   }
}

My problem is that I cannot get the email into the CF7 dynamic extension so that I can deliver the form directly to the vendor email.
Can your please help with the right short code for your plugin?
Many thanks
