Query one collection and fetch data from related collection

Hi everyone i have a database on appwrite named inventories which have relation with warehouses db like following:

1. Two-way relationship
2. Realted Collections -> warehouses
3. Attribute Key -> warehouse (i name it warehouse)
4. Attribute Key -> inventories
5. Relation -> Many to Many (not sure if this could be a problem but open to suggestions)
6. On deleting a document -> Cascade - delete all related documents

So how my setup is for example if i have "Hoodie" as inventory item i am going to create a row entry for Warehouse 1 and if it is going to Warehouse 2 then i will make another row entry in inventories collection. Open to suggestions on how to achieve an api call like this: const inventories = await databases.listDocuments( PRIVATE_APP_WRITE_DATABASE_ID, PRIVATE_APP_WRITE_INVENTORIES_COLLECTION_ID, [Query.contains('warehouse', [warehouseId])] ); bcoz when i do this it doesnt work and i want to fetch warehouse details in it.

Tech Stack: I am using Sveltekit 2.0 and warehouseId is passed as param as string.
