We are using Embedded Genesys cloud in D365, which is called Interactionsync for Genesys cloud.
Here in this integration, we noticed an issue for Web Messaging. For Web Messaging we have added the interaction attributes <Call.QueueName> as per the Genesys article.

When we add the Call.QueueName attribute it should only the queue name; however, for web messaging it shows Guest.
We have tried added the same attribute for Phone,Facebook and SMS interactions. For phone and SMS the attribute displayed correctly, we noticed the problem only for Web Messaging interaction.
Please find the below screenshots for interactions:
