Popup not usable with Vaadin24, plugin v24.0.4

[timothygruetzner]

It seems like plugin version 24.0.4 does not work correctly with Vaadin 24.4.3.

When creating the popup like popup.setFor(id) and the corresponding button with the same ID is clicked, nothing at all happens.
When programatically opening the poup via popup.setOpened(true), the following JS error appears on the browser console:

Uncaught TypeError: $0.show is not a function

Find an example of what I'm doing below:

VerticalLayout v = new VerticalLayout();
Popup popup = new Popup();
popup.add(new H1("Test Text"));
popup.setFor("test-btn");

Button testBtn = new Button("Open");
testBtn.setId("test-btn");
testBtn.addClickListener(e -> popup.setOpened(true));

v.add(testBtn, popup);

Am I using incompatible versions? I'm not using the latest version of the popup, as the Vaadin Add-on Directory mentions plugin 24.0.4 to be used with Vaadin 24.
