Bluetooth amplifier with capacitive touch switch

I have a question and I think this community can solve it. It’s about a Bluetooth amplifier (tda7492p). I want to add capacitive touch switches(ttp223) to it. I saw one guy doing it on YouTube (https://youtu.be/dXUp-1cJUNQ) but I have no idea how I can do it because he didn’t add a wiring diagram to his video. Please give some advise. Thanks in advance!!
