Send "type": "Table" as AdaptiveCard via MS Teams Incoming Webhook

Question

Hey,
I'm trying to share a table via Incoming Webhook Connector, similar to the table shown here: https://adaptivecards.io/explorer/Table.html
Ideally I would also use @mention in the same message as described here: https://learn.microsoft.com/en-us/microsoftteams/platform/task-modules-and-cards/cards/cards-format?tabs=adaptive-md%2Cconnector-html#user-mention-in-incoming-webhook-with-adaptive-cards

I'm running into "webhook message delivery failed with error: Microsoft Teams endpoint returned HTTP error 400 with ContextId MS-CV=HnpK8NsUJ0qyTeXzd3RHoQ.0.." and/or"Summary or Text is required." while trying to add the table into the msg.
Can someone share a working example for Incoming Webhook Connector?
