How to call a method written in Main class inside of a Controller? [duplicate]

I have a login view, when I click the Sign In button I want my window to change its view. So, when I press the button, it calls the function inside of a controller that calls a function located inside of Main class.
Is there any way to achieve what I want? And is it necessary to have the same parent node in all fxml files? (ex. AnchorPane, GridPane etc.)
I have looked to the code of login of JavaFX examples, but can't understand how they do it.
I also tried to change the scene, but the nodes inside of it behave like they don't belong to that window.
Main.java
public void changeWindow() {
Parent root = FXMLLoader.load(getClass().getResource("template/sampe.fxml"));
window = primaryStage;
window.setTitle("Some");
window.setResizable(false);
window.initStyle(StageStyle.UNDECORATED);
Scene scene = new Scene(root);
window.setScene(scene);
window.show();
}
LoginController.java
public void signInClicked() {
Main.changeWindow();
}
I want when button clicked, window changes its view.

I case you don't know how to combine the linked questions: The issue is that you do not have access to a instance of yourMainclass and try to call a non-static method. (Using just any instance wouldn't work btw.) The second duplicate describes ways of passing the application instance to the controller. I honestly do not know where the assumption that fxml files are limited in the node type comes from(You already know 2 different types are possible, what makes you think there's a limitation on some group?It's not even necessary to create nodes, but other objects cannot be added to a scene).
