Bug: CTI Flow does not execute agent.onRefresh in CTI Adapter for Salesforce v5.19

[intptr-t]

CTI Flow for agent.onRefresh event is not executed in Amazon Connect Salesforce CTI Adapter v5.19.
Agent.onRefresh events do not seem to be binding.
Is there any way to deal with this?

CTI Flow Information

• CTI Script Name: Any Value (e.g.: Amazon Connect Agent onRefresh)
• Source: Amazon Connect Agent
• Event: onRefresh

Example CTI Flow

        }
    ]
}

Similarly, the following settings do not seem to work.

Source: Initialization
Event: onInit

It seems to be supported as far as the documentation is concerned.
