Silly request: Any app that can control Caps Lock LED on Apple keyboards?

I have a M2 Mac Mini paired with an Apple Wireless Keyboard. I just discovered that macOS can control the caps lock LED on the keyboard. To test it for yourself, put Caps Lock on, then go to a password entry field anywhere - in a browser or in System Preferences. There should be a little blue icon telling you Caps Lock is on. Click on it, and it will turn off Caps Lock as well as turning off the LED on your keyboard. I don't know if this works for third party keyboards but it does for my 10-year old Apple Wireless Keyboard. Now my silly request: is there an app that can use the keyboard Caps Lock LED to play morse code or flash it in time to music or flash to signal email / WhatsApp messages / or other form of silly entertainment? Posted in macOS because it's a macOS function. Tagged with spoiler because it's a fun little surprise.
