Post jenkins build output (console output) to slack

Jenkins generate some outputs for each build, which is shown in "Console output" panel for each build.
Can I make the slack-plugin post that output to slack? Is this feature already available?

I tried checking the box " Include Test Summary" in the slack notification configuration. However, what I got on slack is "No Tests found."

Start by tracing the Slack notification configuration and how the Jenkins build's Console output is exposed, then compare that with the existing Include Test Summary behavior. Done means the plugin can post the requested build output to Slack with clear handling for output size and unavailable content.
