Do you want the URL of your page to look like this when you share it?
First upload the image, you can make this in the Ordering Builder, please check this screenshot.
You can make this with your Ordering Builder very easy!
Access to your account and click the "Edit" button to open the Ordering Web menu.
And add this code in the <head> section with your information, after this please update
<meta property="og:title" content="Title for the Share link" />
<meta property="og:description" content="Description." />
After save the changes, you must re-build your website to see the changes.
If you want to test the changes before sending the URL, you can use this site https://developers.facebook.com/tools/debug/
