### Detailed Problem Description

There is a new Firebase SDK, [Data Connect](https://firebase.google.com/docs/data-connect). But I see no [api reference](https://firebase.google.com/docs/reference/js). This is the [only place](https://firebase.google.com/docs/data-connect/web-sdk) where you can find some methods like _executeQuery_ . Even so, what if the query has parameters? How would you use it with a query like _getMovieById({ id: movieId });_ ?
