[Rendering] Power Automate "Post to a Teams channel/chat" only supports v1.4

Target Platforms

SDK Version

N/A

Application Name

Microsoft Teams

Problem Description

This documentation says v1.5 is supported in Teams, but the "Post to a channel/chat when a webhook request is received" Power Automate workflow still only supports v1.4.

Posting to Teams via o365 connector is getting removed, we rely on v1.5 features to be able to display our automated messages correctly.

Start with the linked Teams adaptive-card support documentation and the supplied v1.5 card JSON. Verify whether the Power Automate workflow is within this repository’s scope and identify where its supported card version is controlled. Done means the workflow accepts the reported v1.5 features, or the issue is redirected if that behavior is external.
