It's really not that hard

It's in the word "Saudi" for example - right when you transition from the a to the oo sound, your throat just does a bit of the work along with your mouth.

There's another letter that's way harder in my Arab-Australian opinion: https://en.wikipedia.org/wiki/Qoph#Arabic_q%C4%81f

That one legit is close to a cough, just higher up in the throat.
