How to add custom functions to Laravel's Pivot model?

Question

Laravel

There are three tables:
Products
id
slug
Features
id
name
Lang
id
name
With the help of Laravel and ORM models, I translated each feature
id feature_id lang_id content The
question is how to make any product, any feature, have content in different languages?
Pivot?
Something from the category:
id feature_product_id lang_id content
Is there an option to do this using Laravel methods?
Thank you very much in advance for your reply
