Switch audio output based on app

[Android Central Question]

I can change the audio output of my device between my wired headphones and my car's Bluetooth from the pulldown notification, I was wondering if this could be done automatically based on what app is open...
Context, I travel a lot mostly with other people, and my phone's almost always connected to the car's stereo.
Which mostly means private WhatsApp voice messages being played on the stereo...just looking to avoid this...
