Access JSCall Invoker via the bridge in React Native Module - react-native

Question

I am trying to access the jsCallInvoker method which is a reference to the JS thread on the react native bridge, but in xcode i dont see the reference to the method, i have forked the react-native-mmkv library but havent got access to the above variable. I would want to know if i need to add any more header files, or is there any other way i can get access to the JSinvoker method
I am using React version 0.66 with hermes enabled

You need to import
#import <React/RCTBridge+Private.h>
#import <React/RCTUtils.h>
#import <ReactCommon/RCTTurboModule.h>
#import <jsi/jsi.h>
Also Your Podspec file needs to have the following dependencies
s.dependency "React-Core"
s.dependency "React"
s.dependency "React-callinvoker"
Then do pod install
