conversationId not returned from Conversation.Create

[tomw1994991]

Hi,

The intercom api docs have conversationId as one of the response fields after creating a conversation: https://developers.intercom.com/intercom-api-reference/reference/createconversation

This library returns a UserMessage which has no conversationId field, making Conversation.Create hard to use in a practical scenario.

Version info

• intercom-java version: 2.8.0
• Java version: 17

Expected behavior

Be able to get conversationId after creating a conversation.

Actual behavior

Can only retrieve messageId and there is no good way to find the conversation (listing through all the conversations looking for the message is not great).

Steps to reproduce

1. Call Conversation.Create which returns a UserMessage
2. There is no reference to the newly created conversation
