There are different scenarios present for the above issue-

• When reacting with Clapping hands in Teams, It reflects as Clap in MM
• When reacting with Sarcastic in Teams, It reflects as Clap in MM
• When reacting with Clapping in Teams, It reflects as Clap in MM
• When reacting with Clap in MM, It reflects as Sarcastic in MM
• When reacting with Clapping hands / Sarcastic / Clapping on Teams, request on MM comes with emoji name = Clap
• When reacting with Clap on MM, Request body is sent with emoji name = Clap
• On changing the emoji name to clapping_hand in the request sent from MM to Teams, no emoji is reflected on the Teams message.
• Even when sending a request from the Graph API with the request body containing the clap emoji, the emoji shown on the Teams message is the sarcastic emoji
