Huawei P20 Lite Android Pie - reboot your phone?

Have a few days ago, my huawei p20 lite on android pie and emui 9.1 updated and do not know how to restart the phone, usually you keep the button just pressed but that was changed by the update and now do not know how I restart my phone

The functions of the 'power button' are now repeatedly usable on Android Pie. Should you look at the settings once.
