Library of motion notification sounds for RING products

Is anyone aware of a free library of sounds to use with the RING products, other than the ones included? For example, I'd love to have more custom sounds on my Android devices to differentiate between doorbell/front walk motion, driveway motion, yard motion, etc. (to work with ring doorbells, ring floodlights, etc that are installed around our home) I use different chimes now, but they are boring ones. "Driveway motion" with a chime, etc. I could record my own, but no need to re-invent the wheel if this already exists? Thanks in advance
