How do I show the Animation Sequence Editor?

Hi, I am really new to Unreal Editor. I am trying to learn about adding Notifies to animations, this page seems to cover it: Animation Sequence Editor | Unreal Engine Documentation

However I can’t work out how to show the screen discussed on this page, which is called the “Animation Editor” or “Animation Sequence Editor”. It should look like this:


When I open an Animation in Persona it just looks like this and there is nowhere to right-click and “Add Notify”:

So how do I open the window mentioned above so that I can add the Notify?

I also have this problem, and would love to know how to solve it
