How to get related data in Angular Ngrx?

Question

Angular

Good afternoon!
The following situation occurred.
There are two stores
tags: [
{id: 1, name:'Tag', id: 2, name:'Tag 2' }
]
and
pages: [
{id: 1, tagId: 1, title:'Title' }
{id: 2, tagId: 2, title:'Title'}
]
In the component, I get all the pages and loop through them.
But how can I link to each page a tag from store tags by id.
As a rule, we say selectedId = id in the store and subscribe to the selected email. But in my case it doesn't work.
