How to hide many-to-many relationships in Redux state with Normalization?

Question

Scenario

We have a database that displays the following ratio:

• A taghas a lotcampaigns
• A campaignhas a lottags
• The relationship between campaignsand tagsis represented by an associative entity calledcampaign_tag
• The object campaign_taghas an attribute.priority

Question

How can we implement normalizr (or any similar library) to create a smooth state of an application that takes into account our associative objects when our associative objects do not have unique identifiers / values?
