How do you pass data into a chosen scene

Assume we have a main menu with multiple buttons, and we have a text file which contains data behind button 1, button 2, etc.... The text data is loaded into an array of dictionaries.

We are loading a scene like this:

# Global singleton provides a data set, i.e.
var mydata = [{...}, { ... }, etc...]

# On the main menu scene we have buttons
func _on_Button1_pressed():
    get_tree().change_scene("res://DataList.tscn")
    newscene???.send_data(mydata[0]) # ????

How do I pass the preloaded dictionary object associated with Button1 into the scene that is about to appear?

I understand that change_scene() is "deferred" so we cant just straight away call a "setter" function for this scene, or can we? I am still learning godot so I am a bit lost as to know how to do this

Note that I am expecting to "build up" and "rebuild" the new scene when the user presses the button, and "teardown" when a user exits the scene.

If you already have an autoload (singleton), I would put there the information you want to give the other scene, and have the other scene read it.

Correct, you can't. For the instant where the new scene is loaded the current one is already unloaded, so it can't really call a method on the new one.

Unless you take control of the process. See Change scenes manually.
