How to change journal template in opencart?

Question

opencart

Good day! There is a site on opencart 3, it has a journal theme. I want to change the tab description in the product card, so that the translator widget from Google would appear there by default. At the moment, I inserted it through the description field in the products, but inserting it for each product is completely inconvenient.

Chot tried to change the template in the design-theme editor-product-product.twig, stupidly inserted text between the tags with the description class, but this did not affect the site in any way.
How to open it, tell me please?

Answer 1

Clear theme cache.
In the dashboard of the admin panel in the right upper corner is a button with a gear.
