can't get @elastic/eui + react-testing-library\jest to work together

[oyemini-fortifieddata]

I found a working example here for @elastic/eui + working example here for jest & react testing library.
but I can't make them both work here,
I'm getting:

ace is not defined

ReferenceError: ace is not defined
