PushNotificationChatData
Holds all the data that is hubspot specific, extracted from a push notification collection. A convenient way to bundle all the known parameters together for passing along from notification delegate to the hubspotchatview
These keys are also defined as constants here as key value pair: titleKey = Represent the Notification Title bodyKey = Represent the Notification Body portalIdKey = Represent the Notification Portal Id threadIdKey = Represent the Notification Thread Id chatFlowId = Represent the Notification ChatFlowId
The presence of any of these keys is use to indicate that the push message is for a hubspot chat. They are used by the helper method `HubspotManager/isHubspotNotification(notification)`
