Make the beeping sound shorter

[log101]

Hi, I really enjoy using the app but the sound when you're done studying is really too long and annoying. It beeps 5 times, so if you make it 3, I think it would suffice.

I'm on elementary OS 5.1.7 Hera using the latest version of Rush from the app center.

Agree, tried doing it myself, but can't wrap my head around how libcanberra works (lib used to play system sounds). Maybe it had to be done by replacing with custom sound.

I'd also recommend an option of different sounds that aren't as jarring. The beep is MUCH louder than other system sounds, and I nearly jumped out of my chair the first few times it went off.
