Using React libs in AppDelegate

How does one access the React/ libs in the Objc files? e.g. AppDelegate.

#import "AppDelegate.h"
#import "ExpoKit.h"
#import "EXViewController.h"
#import "React/RCTLinkingManager.h" <<< Error here

If you have a detached app with ExpoKit, then just import the same way you would in a vanilla react native app. In this case I think you probably should use <Triangle Brackets> when importing, same as a normal react native app.
