How to get teams channel message from reply of a message id in ms graph?

Hello @bayusaurus, 
When using the Microsoft Graph API to retrieve messages in Microsoft Teams, you may encounter a situation where you need to differentiate between main messages and replies. If you receive a 404 error when trying to retrieve a reply message using its message ID, it indicates that the API endpoint you are using is not designed to handle reply messages directly.

Could you please check with this Graph API-

GET https://graph.microsoft.com/v1.0/teams/fbe2bf47-16c8-47cf-b4a5-4b9b187c508b/channels/19:4a95f7d8db4c4e7fae857bcebe0623e6@thread.tacv2/messages/1612509044972/replies/1613671348387
