How can I enable bi-directional communication between a new window, and the main window?

[JacobMillward]

I'm trying to create a setup where a desktop app opens the settings menu in a new window. I have it working and sending updates back by passing a Rc<dyn Fn(SettingsUpdate)> in the initial props. I would also like for the main window to send the mutated or changed settings forward to the settings window after it already exists.

How can I do this?

Edit:
For future readers with the same issue, my initial implementation was based on the popup example in the repo. https://github.com/DioxusLabs/dioxus/blob/main/examples/popup.rs

You can create a pair of async channels with futures::channels::mpsc::channel(): One for sending messages to the window and one for receiving messages from the window. You can pass the sender and receiver through props and read each channel in a use_future

I think you've pointed me in the right manner, but I'm struggling here. Any chance of an example of implementation?
