Vacation mode on smart plug

Hello. This is my first posting here. My question seems simple but has been elusive so far. I bought 4 smart plugs. They are all supposedly connected to our Wi-Fi network. My goal is to use these rather than old- fashioned lamp timers to randomly turn lamps on and off during a specified period. BUT I cannot find the Vacation Mode anywhere. I have the Smart Life and Wyze apps on my phone.

If you put the plugs in a group, you can turn vacation mode for all of them on/off with one switch.
