Passing the _fields parameter

[richpixel]

How can we specify which fields to return in the data set from a 'get' request?

The wordpress api provides a '_fields' parameter in order to do this:
https://developer.wordpress.org/rest-api/using-the-rest-api/global-parameters/

I would like to do something like:

const mediaItems = await wp.media().perPage(200).page(page++).fields(["id", "slug"]);

But this doesn't work - how can we specify 'fields'?
Thank you
