How do I activate the folding mirrors in my Audi A3?

I have a 2020 Audi A3 and I noticed that my side mirrors have the capability to fold in, but I can't figure out how to activate it. I've checked the manual and tried different button combinations but no luck. Any help would be greatly appreciated!

To activate the folding mirrors in your Audi A3, simply press and hold the 'fold-in' button located on the driver-side door panel. Once activated, the mirrors should automatically fold in when you lock your car.

If you have the comfort package on your Audi A3, you can activate the folding mirrors by using the key fob. Press and hold the 'lock' button for a few seconds and the mirrors should fold in.
