This is needed to be able to use the globalThis keyword and should be okay for the platforms we support.

We're adding a new "react-native" bundle to separate the code that runs on "react-native" from that which run on web.

I tried setting this only on the streaming requests, but that yield the following in my test app:
LOG Running "ReactNativeTestApp" with {"rootTag":61,"initialProps":{}}

Besides the changes I'm proposing to the TypeScript docs and JSDoc, I would say the instructions on adding the babel plugin and globals polyfill needs to be inserted on https://docs.mongodb.com/realm/sdk/react-native/examples/query-mongodb/#real-time-change-notifications as well. |
What, How & Why?
This closes #3494 by adding documentation on installing polyfills and a babel plugin, plus calling the React Native fetch polyfill with the right option.
If the user forgets to add the polyfill and calls
watch()TypeScript documentation as seen in VC Code
The JSDoc documentation
