External doorbell sound on motion detection

I'd like my 2nd gen rechargeable doorbell to sound externally (on the physical doorbell) when motion is detected - just a ring sound like when the doorbell button is pressed. I know I don't have the motion warning setting available on this doorbell so can't have the voice saying "you are being recorded" but can I have it ring the doorbell on motion? I'd like it to sound to scare people away, and my friend has this set up on her Ring doorbell. My indoor chime sounds on motion and I get an alert through the app on motion, so that is working as it should.
