FabioR 🇩🇪 thanks! i noticed that for me it only works as expected when it's turned on. thanks again
UPD

sadly it only works in settings. other apps still trigger this pop up box 😐

this is the additional command name for notifications setting nt_notification_expand_enabled=0. looks like there is no way to disable pop up feature from config. perhaps it's possible by disabling some services
