Provide an option to student to raise a flag, if gone on a break.
During the class student might have to go for nature call or water break. So, student can raise that flag, and if during the class faculty called out the student name than faculty can see if the student is available or not.
Also to track the break time, a timer can also be shown for that flag.
This should only be shown to faculty who should be the owner of that Team or group.
