Suppose I have a tempalte Foo and to react components Outer and Inner, where Inner is a child of Outer. If I need useStreamQueries(Foo) in both Outer and Inner, is there an advantage to passing the result as a prop from Outer to Inner, or is it just as good to call useStreamQueries a second time in I…

The second option will generate 2 websockets connections and at the moment also 2 transaction streams to the legder so I’d definitely recommend passing the data down instead of querying the same data multiple times.

How would I do that in typescript? The query result has type QueryResult<Foo, Foo.Key, "FoosTemplateId">. How do I get my hands on “FoosTempalteId” to declare the type of the props of Inner?
