How do I activate the massage function in my Audi A8?

I recently purchased an Audi A8 and I noticed that it has a massage function in the seats. However, I can't seem to figure out how to activate it. Can someone please guide me through the steps?

First, make sure your vehicle is turned on and the massage function is activated in the MMI system. Then, press the 'Massage' button on the center console. You can choose between different types of massages and adjust the intensity to your liking.

To activate the massage function, push and hold the 'Massage' button for a few seconds until you hear a beep. After that, you can release the button and the massage function should be activated.
