Step #1 - Copy the Embed code
After you publish the item, choose the Share tab, select Shopify, and copy the code:
Step #2 - Open a Page on your Shopify Site
Either use an existing page or open a new page for adding the item.
Step #3 - Add the item to your page
In the editor of the page, click on the ‘</>’ icon. In the HTML editor that opens paste the item code you copied in step 1 and click save/create page.
Save the page & preview to see how the item looks on the page you created and make changes to your page accordingly.
That's it!
