Issue with Deleting Products from Google Merchants Center

Dear Admin,

I have a website with over 100,000 products, and I need to remove some products from Google Merchants Center. Due to the large volume (more than 10,000 pages), manually setting each product to “Don’t sync and show” is not feasible. Instead, I’ve been using the page “wp-admin/admin.php?page=connection-test-admin-page” where I input the Product ID I want to delete, then click “Sync Product with Google Merchant Center” as shown in the screenshots. I receive a notification stating “1 product successfully submitted to Google.” However, the issue is that the products are still present in Google Merchants Center even after 24 hours. Have I missed something? Is deleting by Product ID as described correct?

Your assistance with resolving this matter would be greatly appreciated.
