RtcEngine.init is not working in react Native

Question

I am working a project of Video Calling using React Native Agora library. But when I run application I face this error "typeErro: undefined is not object ReactNativeAgora RtcEngine.init(config)

RN version: 0.62.2 react-native-agora": "^3.2.2

my Code is

import { View, StyleSheet, NativeModules, Platform } from 'react-native';
import { RtcEngine, AgoraView } from 'react-native-agora';
import Icon from 'react-native-vector-icons/MaterialIcons';
import { Actions } from 'react-native-router-flux';
import { configureFonts } from 'react-native-paper';

const  Agora  = NativeModules;                  //Define Agora object as a native module

const {
    FPS30,
    AudioProfileDefault,
    AudioScenarioDefault,
    Adaptative,
} = Agora;                                        //Set defaults for Stream

class Video extends Component {
    constructor(props) {
        super(props);
        this.state = {
            peerIds: [],                                //Array for storing connected peers
            uid: Math.floor(Math.random() * 100),       
            appid: this.props.AppID,                  
            channelName: this.props.ChannelName,        
            vidMute: false,                            
            audMute: false,                             
            joinSucceed: false,                         
        };
        if (Platform.OS === 'android') {
            const Config = {                           
                appid: this.state.appid,                  
                channelProfile: 0,                       
                mode: 1,
                videoEncoderConfig: {                     
                    width: 720,
                    height: 1080,

                    orientationMode: Adaptative,
                },
                audioProfile: AudioProfileDefault,
                audioScenario: AudioScenarioDefault,
            };
                  RtcEngine   //Initialize the RTC engine
        }
    }```

Have a try by running again project by npx react-native run-android command.

If you are using the iOS Device then:

• cd ios && pod install
• npx react-native run-ios

if still not works try installing the npm package again and follow the documentation.
