Disable confirmation prompt for exit button for Oracle Web channel

Summary:

For the Oracle Web channel, I wish to disable the confirmation prompt for when the exit button is given.

Content (required):

As of the SDK version 21.12 for Oracle Web channels, we're able to add an exit button for the users to click: https://docs.oracle.com/en/cloud/paas/digital-assistant/use-chatbot/oracle-web.html#GUID-2CF33DCA-F8AF-4C56-BCB5-77E2EC107967

This is done by setting `enableEndConversation: true` in the settings. It present a confirmation prompt to the user when clicked confirming they want to exit the chat. I'd like to have the exit button without this confirmation.
