This example illustrates adding an OpenUri Action to a message card. When
used, this action triggers opening a URI in a separate browser or application.


Of note:

- message is in MessageCard format
- default timeout
- package-level logging is disabled by default
- validation of known webhook URL prefixes is *enabled*
- message submitted to Microsoft Teams consisting of formatted body, title and
  one OpenUri Action
