Clap Version

clap_complete 4.5.1

Describe your use case

i am using clap_complete for the first time, and it took me a bit of poking around to figure out how to get a Command from a Parser (plus having good enough intuition to guess that such a function must exist, otherwise i may have given up)

Describe the solution you'd like

add something like "for Parser users, see clap::CommandFactory::command" near the top of the clap_complete crate documentation.
