hide product without redirect

Hi everyone, I have woo with wcvendors installed. Currently I have products blocked with a redirect to the log in page. I would like to remove to redirect and instead just have a message for users that dont have permission to access products. I have looked at plugins but none do exactly this without adding tons f other features.

My currect redirect code is:

function wpse_131562_redirect() {
if (!WCV_Vendors::is_vendor(get_current_user_id())
&& (is_product() || is_cart() || is_checkout())
) {
// feel free to customize the following line to suit your needs
wp_redirect(“/my-account/”);
exit;
}
}
add_action(‘template_redirect’, ‘wpse_131562_redirect’);

Just hoping someones knows a code or can give me direction.
Thanks
