Expected behaviour of the Language IO plugin with Enhanced Messaging

As of February 2025, the following behaviour is expected of the Language IO Messaging package for Enhanced Messaging:

Conversation Participant entries not visible

If the end-user closes the conversation, then reopens it after a short period of time (less than five minutes), this might cause some participant history entries to drop from the "LIO" tab.

For example, compare these two screenshots of the standard tab (top) and the "LIO" tab (bottom). Note how the highlighted entries on the standard tab are not present on the "LIO" tab:

This is caused by the way Salesforce tracks the conversation: because records are added to the Salesforce database asynchronously, if a conversation is closed and then re-opened in a short period of time, the latest records might not yet be saved to the database. 

To solve the issue, simply refresh the browser page after a couple of minutes have passed.
