react native how to implement deep link and fbsdk in IOS - ios

Question

I am trying to implement deep link with React Native on IOS using this link here https://medium.com/react-native-training/deep-linking-your-react-native-app-d87c39a1ad5e, however, I am having trouble at the steps of setting code in AppDelegate.m. As part of integrate FBsdk, my AppDelegate.m is having the following code
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation];
}
then I integrate with App Deep Link (https://medium.com/react-native-training/deep-linking-your-react-native-app-d87c39a1ad5e), then it ask to modify the same function. Below are what Deep Link on IOS requirement for the above method
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:
(id)annotation
{
return [RCTLinkingManager application:application openURL:url
sourceApplication:sourceApplication annotation:annotation];
}
So my question is how do I combine these two function
BOOL fbsdk = [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation];
BOOL deeplink = [RCTLinkingManager application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation];
return fbsdk || deeplink;
Would this be a correct answer? or do I need to do something with the url that comeback from NSString * scheme = (NSString*)url.scheme;
