How to handle data distribution shifts

Hello, I am using fbprophet to forecast the sales of a store. The structure of the data is hierarchical, and I am predicting at the highest level.

Example:
The store can sell Books, Movies, Toys. Books can be Action, Adventure, same with movies and toys. And then you have the actual product.

I am forecasting the revenue at the Books, Movies, Toys level. I would like to know how to handle a scenario where a new book is added to the store and suddenly it starts to generate a high volume of sales thus, increasing the revenue for that unit.

Any research on this? Is there any common approach?

Thank you!
