Notification whenever a new entry is made to the firebase storage

So, I am working on a website and i want to implement something. I am using firebase to send normal html form stuff to the firebase database, One page has a form which also has a an attachment option where the user has to put in his resume, I am able to send the pdf file to the firebase storage but i want that the owner of the site/admin is notified whenever somebody new registers is there any way i can implement this by either sending the owner an email that somebody applied/registered if yes please guide me or some resources to do the same and also if this can be done by firebase itself or i have to do something with the third party.
