Shopify product page template is not showing in theme editor

[Sivadarshan]

I am already managing a live website in a partner account while developing a new website in draft mode. Since sharing the URL would redirect to the live website, I created a new account, downloaded the draft version of the developing website, and uploaded it to the new account. However, after uploading the theme file, the product page template is not appearing in the editor. How can I retrieve the product page template in the editor?
