In the `queryFn` function that executes the query, you use the JS SDK's `client.fetch` method to send a request to your custom API route. The first parameter is the route's path, and the second is an object of request configuration and data. You pass the query parameters in the `query` property.
This sends a request to the [Get Brands API route](#1-get-brands-api-route), passing the pagination query parameters. Whenever `currentPage` is updated, the `offset` is also updated, which will send a new request to retrieve the brands for the current page.
