Descaling a Lelit PL62

I’m currently descaling a Lelit PL62 following this video: https://youtu.be/vTo2mJpnLvU?si=3jlsJEsfNEq_o0Ol The descaler is in the boiler, and it’s soaking. According to the video, the anti-vacuum valve is removed, and the boiler is emptied using a syringe and a tube. However, I can’t seem to find this valve, or it looks different on my machine. Could you help me figure out how to access the boiler?
