Hi,
Currently sending an urgent/important Teams Chat Message is not available using the standard "Post message in a chat or channel" action (here).
My plan is to send a message to a group chat with high importance/urgency.
I noticed there is a "Send a Microsoft Graph HTTP request" instead; and according to the documentation, it is possible through Graph API (here).
When I tested it on Graph Explorer, it works as intended:


Now, when I tried to use the "Send a Microsoft Graph HTTP request", for some reason it thrown the following error:
{
"error": {
"code": 400,
"message": "URI path is not a valid Graph endpoint, path is neither absolute nor relative or resource/object is not supported for this connector. Resources: teams,me,users Objects: channels,chats,installedApps,messages,pinnedMessages. Uri: https://graph.microsoft.com/v1.0/chats/19xxx6c@thread.v2/messages",
"source": "flow-apim-msmanaged-na-westus2-01.azure-apim.net",
"path": "choose[37]\\when[1]",
"policyId": "",
"clientRequestId": "xxxxab-xxx"
}
}
URI: https://graph.microsoft.com/v1.0/chats/19xxx6c@thread.v2/messages
Method: POST
Body:
{
"importance": "high",
"body": {
"content": "Hello World"
}
}

Could someone please assist me in identifying the problem here?
Thank you in advance!
