This is an example of a client application which uses this library to:

- generate a Microsoft Teams message in MessageCard format
- submit the message using an explicit proxy server URL

Of note:

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