 * Create push notification channel with provided id, name and importance of the channel.
 * You can call this method also when you need to update the name or description of a channel, at

 *
 * @param context The application context.
 * @param channelId The id of the channel.
 * @param channelName The user-visible name of the channel.
 * @param channelImportance The importance of the channel. Use value from 0 to 5. 3 is default.
 * Read more https://developer.android.com/reference/android/app/NotificationManager.html#IMPORTANCE_DEFAULT
 * Once you create a notification channel, only the system can modify its importance.
 * @param channelDescription The user-visible description of the channel.
 * @param groupId The id of push notification channel group.
 * @param enableLights True if lights enable for this channel.
 * @param lightColor Light color for notifications posted to this channel, if the device supports
