What is the notify-send alternative command in Pop! OS

I use notify-send in **Manjaro Linux** to send notifications, as follows: notify-send [OPTIONS] [Message Summary] [Message Body] However, I moved to Pop! OS and I found that command not found: notify-send I heard that notify-send is dead, so I am trying to get an alternative command to send notifications in Pop! OS Is it also possible to install notify-send in Pop! OS?
