How do I get AI to jump between nav proxies?

How do I get an AI character to jump when it gets to obstacles such as a hole or small wall? I have the AI character chasing the player which is working fine, the player can jump and I want the AI to be able to do this as well so they can follow the player almost anywhere.

I have nav mesh proxies but they do not seem to work, I am new to unreal engine 4 and game development.

Can anyone please advise the simplest way to achieve this goal? The game is kind of basic so I do not need super complex blueprints :smiley:

Thanks.
