Custom Notification Sounds

When a meeting attendee enters the waiting room it creates a ping notification. I would like to change the audio file that is played  for the notification from a ping to something more noticeable I would hear even from another room. 

Maybe this is a stretch, but I was thinking the audio file for the ping notification might be in the file system somewhere, so I could replace it with a custom notification sound.

The idea is for me to be logged into Zoom all day, clients can jump on and speak with me spontaneously, and I'll hear that someone joined even from another room.
