Creating a Cloud Template for a specific woocommerce single product

On the Envato website Simion C. wrote to another customer:

While on a product page, from the template selection dropdown in the admin bar click on the name of the template you want that product to use https://i.imgur.com/GC10OjT.png Then that product will use that template. From there a template can be set per product or globally. Please try it. For support requests please contact us either by email at contact@tagdiv.com or by forum if possible https://forum.tagdiv.com/forum/newspaper/ That would be better. These new woo features are at the beginning of the development, they will be improved more in the future. We will also take into account all suggestions and feedback from our users. Let us know.

So I see that we can do this for unique single product pages but how do we do this?

Thank you!!!

ok so now Simion C. fixed the image example on that page. Thank you!
