SalesIQ Integration using Flutter is working on ios , but does not work on android.

I have added everyhting correctly, and the integration works fine, the luncher show on IOS , i also hv a button to call ZohoSalesIQ.show(); . on android nothing is working, i have installed the zoho mobilLisiten package, infact the sdk init successfully , but nothing showing.

i tried adding the lifecycle sample code, but my project have kotlin and not java, so it kind of problematic to add. below is my main kotlin class

package com.xxx.xxxx

import io.flutter.embedding.android.FlutterFragmentActivity

import com.zoho.livechat.android.MobilistenActivityLifecycleCallbacks

class MainActivity: FlutterFragmentActivity()

Also below is my flutter init class.

@override
  void initState() {
    super.initState();

    print('loading zoho sales IQ');

    ZohoSalesIQ.setLanguage("en");
    ZohoSalesIQ.enableInAppNotification();
    ZohoSalesIQ.eventChannel;
    ZohoSalesIQ.knowledgeBase.setVisibility(ResourceType.articles, true);
    ZohoSalesIQ.setConversationVisibility(true);
    ZohoSalesIQ.setConversationListTitle("CypherX Support");

    if (io.Platform.isIOS || io.Platform.isAndroid) {
      print('platform is valid');
      String appKey = ""; //Note, i added the actual key, just removed it for sake of this post.
      String accessKey = ""; //Note, i added the actual key, just removed it for sake of this post.

      // appKey = dotenv.env['ZOHO_IOS_APP_KEY'];
      // accessKey = dotenv.env['ZOHO_IOS_ACCESS_KEY'];

      ZohoSalesIQ.init(appKey , accessKey ).then((_) async {
         print('zoho initialization successful');
        // initialization successful
        //ZohoSalesIQ.launcher.show(VisibilityMode.always);
         ZohoSalesIQ.knowledgeBase.setVisibility(ResourceType.articles, true);
        ZohoSalesIQ.setConversationVisibility(true);
        ZohoSalesIQ.setConversationListTitle("CypherX Support");

        var dataZoho = await ZohoSalesIQ.show();
        print(dataZoho);
         
      }).catchError((error) {
         print('zoho initialization failed');
        // initialization failed
        print(error);
      });
      ZohoSalesIQ.setThemeColorForiOS("#6500D8");
    }
  }

Please why is it not working on android
