I was helped with a code snippet the other day to add an additional menu item inside the my account section of B2B (sales kit). I need to make this code snippet execute conditionally based on the group of the user (b2b Wholesale users only).

The code is below. Is this possible? 

function b2bking_add_sales_kit_endpoint() {
    add_rewrite_endpoint( 'sales-kit', EP_ROOT | EP_PAGES );
}
  
add_action( 'init', 'b2bking_add_sales_kit_endpoint' );
  
function b2bking_sales_kit_query_vars( $vars ) {
    $vars[] = 'sales-kit';
    return $vars;
}
  
add_filter( 'query_vars', 'b2bking_sales_kit_query_vars', 0 );
  
  
function b2bking_add_sales_kit_link_my_account( $items ) {

    $i = 1;
   
    $items = array_slice($items, 0, $i, true) +
    array('sales-kit' => 'Sales Kit') + 
    array_slice($items, $i, count($items)-$i, true);

    return $items;
}
  
add_filter( 'woocommerce_account_menu_items', 'b2bking_add_sales_kit_link_my_account' );
  
  
function b2bking_sales_kit_content() {
   echo '

Sales Kit

Click on the items below to retrieve your sales kit

'

   ;
}
  
add_action( 'woocommerce_account_sales-kit_endpoint', 'b2bking_sales_kit_content' );
