Microsoft Graph - Microsoft Teams At Mention Channel

AtMentionChannel.json

{
    "body": {
    "content": "This is Flow mention channel test, <at id=\"0\">SharePoint Site Collections</at>",
    "contentType": "html"
            },
    "mentions": [
                {
                "id": 0,
                "mentionText": "SharePoint Site Collections",
                "mentioned": {
                                "conversation": {
                                                    "id": "@{variables('Channel')}",
                                                    "displayName": "SharePoint Site Collections",
                                                    "conversationIdentityType": "channel"
                                                }
                            }
                }
                ]
}

Slight change needed after update:

{ "subject": "Test Channel Mention", "body": { "contentType": "html", "content": " <at id=\"0\">Social Media Team</at>" }, "mentions": [ { "id": 0, "mentionText": "Social Media Team", "mentioned": { "conversation": { "displayName": "Social Media Team", "id": "@{variables('channel')}" } } } ] }

@pchaturvedi85 thank for letting me know, appreciate it! I have adjusted the code snippet.

Updated the snippet again, I mistakenly had removed the conversationIdentityType property.
