The test I am taking requires webcam access. Will HackerEarth be able to delete only my snapshots/video after the test?

Send a request via email to the test organizer. 
Currently, there is no such option in HackerEarth Recruit. However, the test organizer can request HackerEarth to delete the snapshots. 
This will be done 30 days from the date on which the request is received.
