Howto get Project and Editor in Activity triggered through a Tool Window

I have a plugin with a Tool Window created using Swing elements. When a button is pressed, I want a text to be inserted in the editor.

In a Tool Plugin Window I have the button

acceptButton.addActionListener(toolWindowAcceptAction)

With the definition of the toolWindowAcceptAction as an instance of the class

class ToolWindwonAcceptAction(
    var window: TollWindowFactory? = null,
) : ActionListener {
    override fun actionPerformed(e: java.awt.event.ActionEvent?) {
        // Insert text in Editor
    }
}

When this event is triggered, I want a text to be inserted in the current editor.

However I cant figure out how to get a reference to the current Project and/or Editor. The event is an "ActionEvent" and not an "AnActionEvent" (which would reference the current proect and editor).
