How to use Magnetic Buzzer Transducer

Hey guys!
So I recently got this audio buzzer, DigiKey Part 102-1458-ND
https://www.digikey.com/product-detail/en/cui-devices/CST-931AP/102-1458-ND/1003799
I am having some trouble getting it to work. Can I ground it and give it 3V, or do I have to enable it in the code?
Thanks!

My biggest questions, do you have a diode in parallel with the CUI CST-931AP?

There’s also a good example on the bottom of page 2:

I did see that diode, but it didn’t give me a value or part of one to order.
Do you know of one that would work?
Thanks!

Hi @nweixelman , just standard diode like:

Should work fine…
