macOS: How to map `command-e` to `End` key in Powerpoint

Question

I am trying to bind command-e to End key in the Powerpoint app. By default when I press commend-e, powerpoint creates an item and tabs in. I have tried following approach using this answer, which does not work. What may be the problem for it and how can I fix it?
