Vendor shop template

Hi I wrote a ticket a few weeks back here because I want to add actions to the vendor shop template so I can hide/remove the filter and ‘sort by’ bar. As all my vendors will only have 1-5 products so there is no need for this and it will confuse customers

You said I could use this code
if ( ! WCV_Vendors::is_vendor_page() && ! WCV_Vendors::is_vendor_product_page( $post->post_author ) ) { //add unhook here }

But I don’t think I’m using right as I can’t get the code to work. I’m now using the pro plugin, will that matter? I’ve tried the below…

if ( ! WCV_Vendors::is_vendor_page() && ! WCV_Vendors::is_vendor_product_page( $post->post_author ) ) { 
.thb-shop-title{ display:none;
}

if ( ! WCV_Vendors::is_vendor_page() && ! WCV_Vendors::is_vendor_product_page( $post->post_author ) ) { 
<style>.thb-shop-title{ display:none</style>
}

function vendor_store_style() {
if ( ! WCV_Vendors::is_vendor_page() && ! WCV_Vendors::is_vendor_product_page( $post->post_author ) ) { 
		?> <style>
.thb-shop-title{ display:none !important;
			</style>
		<?php
	}
}
add_action( 'wp', 'vendor_store_style' );

Any help would be hugely helpful
