How to use the appcenter.LogLevel function in appcenter

import { AppRegistry } from 'react-native';
import AppCenter from 'appcenter';
import codePush from 'react-native-code-push';
import { name as appName } from './app.json';
import 'core-js';
import 'intl';
import 'intl/locale-data/jsonp/en-US';

// set check frequency options
const codePushOptions = { checkFrequency: codePush.CheckFrequency.ON_APP_START };
const eSteemApp = codePush(codePushOptions)(require('./App').default);

AppCenter.setLogLevel(AppCenter.LogLevel.VERBOSE);

AppRegistry.registerComponent(appName, () => eSteemApp);

if (appSecret.key === appSecretKey) {
        this.state.appSecret = appSecret;
        break;
      }
    }

    const userId = await AsyncStorage.getItem(USER_ID_KEY);
    if (userId !== null) {
      this.state.userId = userId;
      await AppCenter.setUserId(userId);
    }
    this.props.navigation.setParams({
      refreshAppCenterScreen: this.refreshUI.bind(this)
    });

    await AppCenter.setLogLevel(AppCenter.LogLevel.VERBOSE);
  }
