How to observe data from two o more tables?

[Lao-Ax]

Hi! I'm not so familiar with WatermelonDB, so, I'm asking for help.

Imagine we have many-to-many relation between two tables: Docs and Tags. It means each doc could be tagged by any number of tags, and each tag could be assigned to any number of document.
We have a screen (React-Native) where docs and it's tags should be displayed. Say, it is a list of docs with a list of small color tags.

What is the best way to achive reactive updates (when tags or docs or their junction updated) in such a schema?

I developed a schema of 3 tables:

• Docs,
• pivot table of Doc_Tag (mapping of keys (docId; tagId)),
• Tags.

I tried to use an SQL view, but looks like WatermelonDB doesn't support such a feature.

Then I found this doc: https://watermelondb.dev/docs/Relation#many-to-many-relation. But it looks a bit frustrating.
I want to have an observable for each of tables to make a proper update on the UI.
