Do you have to re-declare callbacks from imported components.

[samrock5000]

i have something like

import { InitWindow } from "init.slint";
export { InitWindow }

export component MainWindow inherits Window {
   callback realy-cool-function <=> init-window.realy-cool-function;
}

I found this to be the only way to access realy-cool-function from rust.

If the callback is in a global, you can also access re-exported global directly from native code using the .global<...>() function
Otherwise, yes, you need to re-declare callback in the root component.
