title: Can't add modules to installed Unity editors
body: <p>I'm trying to add the Android SDK Module to an Editor that I have installed on my PC.    </p>
  
  <p>I've looked it up online and the guide available <a href="https://docs.unity3d.com/Manual/GettingStartedAddingEditorComponents.html" rel="noreferrer">here</a> states that there should be an "Add Modules" option available from the menu but it is absent from the menu when I open it in my Unity Hub:    </p>
