Where is 'with_name'?

I was following along in the video tutorials and I get this...

error[E0599]: no function or associated item named `with_name` found for struct `clap::build::arg::Arg<'_>` in the current scope
  --> src/bin/kvs.rs:14:22
   |
14 |         .args(&[Arg::with_name("ARG3"),
   |                      ^^^^^^^^^
   |                      |
   |                      function or associated item not found in `clap::build::arg::Arg<'_>`
   |                      help: there is an associated function with a similar name: `get_name`
