Trigger help step

[buckaroogeek]

I am exploring cli v3 for a small utility I am writing. Is there a mechanism to trigger the display of help text and exit the application. In particular a scenario where an argument is missing I would like to display a targeted message then the help display and exit. I looked in the examples but could not see anything relevant. Thanks1

And I find func ShowAppHelpAndExit in the pkg.go.dev documentation. I will try that.
