Which AC refrigerant is used on a 2016 S5 B8.5?

Does anybody know what AC refrigerant is used on a 2016 S5?

On my other car, a VW Golf, there’s a sticker in the engine bay that says R134a but nothing on the S5.

I read that newer cars use R1234yf and apparently you can’t mix refrigerant so I’d like to know what type of refrigerant the S5 has.

Thank you, I also located the label on the car, it was at a different location VS my golf.
Confirming it uses R134a
