Media: Video Download Restriction

Can anyone help me in resolving this problem. I have created a form to see a video file and then attempt the quiz based on the video. However, they should not be able to download the video in their devices. How do i restrict it from enabling downloading option in Kobo form. The video.mp4 file is being pulled from the Media folder. I need your support on this, plz.

Welcome back to the community, @PrashanthSJ! Do you mean downloading the media files that is attached with the question?

Dear Kal,
Thank you for your response. I actually mean that, the user should have access to watch the video, but the download option can be disabled
