microsoft graph api - Outgoing Webhook what is the format of the response message?

Question

I have created an outgoing webhook in MS Teams. At mentioning the name specified in the outgoing webhook, it will successfully cause an API call in my app - all fine and good.

According to the documentation, my app is required to respond to that request with a response message. But I absolutely can't find any documentation of the format that is accepted in this response.

The only reference, I can find is this one: https://docs.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-outgoing-webhook

Unfortunately, it does not go into detail of what such a message can look like. It only gives an example that this would be acceptable:

{
    "type": "message",
    "text": "This is a reply!"
}

I would however not like to respond with a simple message, but much rather with something more rich formatted like a card or - in some cases a reaction instead of a message.

Is that possible? Is there any documentation, what other responses are acceptable? Are there other types than just "message" that can be returned?

Could you please try this sample json { "$schema": "adaptivecards.io/schemas/adaptive-card.json", "type": "AdaptiveCard", "version": "1.2", "body": [ { "type": "Image", "url": "c.s-microsoft.com/en-us/CMSImages/…" }, { "type": "TextBlock", "text": "Sample image for Adaptive Card..", "wrap": true } ] }
