hello 👋 what does "Online activity - Attendance at a specified time" mean

like how do I prove to them "hello I am here" during my class time? also, i cant find any link to join any zoom meetings so would they send this tomorrow on the day of class? also is it okay if I do this online live recorded thing at home ?
