Why Google Maps Cordova ionic angular, only working in Android and blank in IOS?

Inizia esaminando la preferenza GOOGLE_MAPS_IOS_API_KEY in config.xml e le versioni dei plugin in package.json, quindi esegui il comando ionic cordova plugin list indicato per la configurazione iOS. Verifica la chiave API iOS e le restrizioni del bundle-ID in relazione al comportamento della mappa vuota. Il lavoro è completato quando la mappa viene visualizzata su iOS invece di mostrare soltanto il logo Google.

package.json information:

"@ionic-native/google-maps": "^5.5.0",
"cordova-plugin-googlemaps": "git+https://github.com/mapsplugin/cordova-plugin-googlemaps.git#multiple_maps",
"cordova-plugin-googlemaps-sdk": "git+https://github.com/mapsplugin/cordova-plugin-googlemaps-sdk.git",

Current behavior:
Google Maps is blank but it shows Google logo, Everything normal in Android.

I have added this line in config.xml :

<preference name="GOOGLE_MAPS_IOS_API_KEY" value="MY_API_KEY" />

Also, i've enable Google Maps for IOS and restrict with my bundle id (com.xxxxx.hris) as well.
Here the restrict information :

Maps SDK for iOS
Geocoding API
Geolocation API
Maps SDK for Android
Places API
Maps Static API

Expected behavior:
It should be running fine like Android
