How to setup the tomal for DatePickerButton

[ray-5050]

I've tried all sorts of variations on what I see in the demo app tomals but am unable to get rust to recognize the DatePickerButton or chrono. In s simple "Hello World" app, I added the two lines in the demo widget app.

let date: &mut Date<Utc> = date.get_or_insert_with(|| chrono::offset::Utc::now().date()); ui.add(egui_extras::DatePickerButton::new(date));

The tomal based on what I see in the demo app is below. I'm using a local cloned recent version and before adding the two lines and the chrono = ... the app compiles fine. The errors, below, occur when I add the chrono = part. If I try to add features = ["egui_datepicker"] in the equi_extras, I get the same error. If I remove the chrono = part and use egui_extras::.., no DatePickerButton is an option to choose. Thanks for your help!

[features]
default = []
chrono = ["egui_extras/egui_datepicker", "dep:chrono"]

[dependencies]
eframe = { version = "0.18.0", path = "../egui/eframe" }
egui = { version = "0.18.0", path = "../egui/egui", default-features = false }
egui_extras = { version = "0.18.0", optional = true, path = "../egui/egui_extras"}
chrono = { version = "0.4", optional = true }

The error I get is the following:
error: failed to select a version for egui_extras.
... required by package egui_datepicker v0.1.0 (/home/xxxx/Documents/rust/egui_datepicker)
versions that meet the requirements ^0.18.0 are: 0.18.0

the package egui_datepicker depends on egui_extras, with features: egui_datepicker but egui_extras does not have these features.

failed to select a version for egui_extras which could resolve this conflict
The terminal process "cargo 'run', '--package', 'egui_datepicker', '--bin', 'egui_datepicker'" failed to launch (exit code: 101).

Finally figure it out. egui_extras = { path = "../egui/egui_extras/", default-features = false, features = ["chrono"]}
Figures just as I posted a question.
