Firebase: How to store Videos in storage and then store video URL in database?

So I am using Firebase for the first time. I have read that you should store videos in Storage and then store that unique URL in their Database. How would I take this approach? For example if a user request a specific video to play how would I grab the URL from the database and then with that url pull the video out of the database?

Thank for the help and excuse my inexperience with Firebase.
