I have one friend who uses Google Chat and it's always a bit of a shuffle to figure out where I have to message him back on. It's not in gmail's android apl for me anymore although it used to be (Meet is there). Meet is also a separate app in addition to being in the gmail app. Chat is the app on Android but I think I might actually access chat through Gmail on desktop.
