Import XpressPlugModule:

XpressPlugSDK.initialize( 
  appDelegateClass: AppDelegate.self, withConstants: constants, andResources: resources, 
  andModules: modules) 

Invoke the Initialize method:

const initializeXpressPlug = async () => { 
    try { 
      console.log ('---- ReactNative | Calling XpressPlugModule Initialize'); 
      const result = await XpressPlugModule.initialize(); 
      const success = result === 'true'; 
      setXpInitialized(success); 
      console.log( 
        `---- ReactNative | XpressPlugModule Initialized successfully: ${success}`); 
    } catch (e) { 
      console.error(e); 
    } 
  }; 

  initializeXpressPlug();
