Yes, this app can be used to implement the desired feature. It provides a general configuration for product-wise or product-category-wise filters for all three types of Odoo users (internal, portal, and general).

In your case, you can configure the filter for portal users through Website Settings > Product Visibility > Portal Users. Suppose you have to grant access to specific products or categories for certain portal users. You can set this up in their related partner form under Product Visibility > Products or Categories. This will give priority to the specific configurations set for those portal users. This can be done for all user types as well.

Please refer to the app's indexing for more details about the features and usability.
