Remove-MgGroupConversation does not work
Describe the bug
I am trying to use the Remove-MgGroupConversation command to remove an email from a M365 group mailbox. I have the proper permissions, however I get the error "ConversationID isn't supported in the context of this operation."
Expected behavior
Email should be deleted and a "HTTP/1.1 204 No Content" should be returned as stated here: https://learn.microsoft.com/en-us/graph/api/group-delete-conversation?view=graph-rest-1.0&tabs=http
How to reproduce
Execute the command with the "-groupid" and "-conversationid" switches.
SDK Version
2.30.0
Latest version known to work for scenario above?
N/A
Known Workarounds
N/A. Calling the graph API directly with a HTTP request or in the graph explorer generates the same reply.
Debug output
Remove-MgGroupConversation_Delete: ConversationId isn't supported in the context of this operation.

The request looks valid in the way that it's composed, I've escalated this internally to the team that owns the underlying API.
