RSI Break — Plasma native break timer

Project page links to Flathub. But Flathub gives a page 404.

Project information: RSIBreak helps prevent repetitive strain injuries by keeping track of usage patterns and periodically informing users to take breaks. During break periods, RSIBreak can either show an unobtrusive message, lock the screen entirely, or present a slideshow.
