Is your feature request related to a problem?

No

Describe the solution you'd like

If we hit TryItOut and Execute there is sample curl displayed.
If example is present for all required parameters curl can be generated before clicking Execute and be shown, eg below Summary

Describe alternatives you've considered

Plugin, but from initial testing, whole Operation component needs to be overriden, and it later on would be hard to mantain.

Additional context

I can prepare PR if You're interested

Start with the Operation component and trace the TryItOut and Execute flow to see how the existing sample curl is produced. Check how examples for all required parameters are exposed before execution. Done means the Summary can display a generated curl when those examples are available, without requiring Execute.
