I am working with a modal that is opened when the hotkey is clicked in React. For example, if you press "a", then it opens the modal. But when a video is playing on fullscreen mode, it hides the modal, so I cannot even see if the modal is opened behind the video tag.

Video playback is handled by 'React-Player'.
I tried setting z-index: 0 for video tag, and z-index: 1000000 for modal, but not working.
