Java Swing/IntelliJ IDEA Plugin: How to resolve 'Slow operations are prohibited on EDT' error when using file chooser Dialog

Question

I am creating a plugin in IntelliJ IDEA using Jetbrains plugin SDK. I have created a Dialog box that shows a button to select a Directory. In the ActionListener of the button, I am calling FileChooser dialog. After i select a directory from this dialog, i get the following error

java.lang.Throwable: Slow operations are prohibited on EDT. See SlowOperations.assertSlowOperationsAreAllowed javadoc.

This is how I am adding the FileChooser dialog in the button's ActionListener

    JButton directorySelectorButton = new JButton("", AllIcons.Nodes.Folder);
        directorySelectorButton.addActionListener(e -> {
            FileChooserDescriptor descriptor = new FileChooserDescriptor(false, true, false, false, false, false);
            VirtualFile[] chosenFiles = FileChooser.chooseFiles(descriptor, null, null);

            System.out.println(chosenFiles[0].getPath());
        });
