For Linux users, I particularly recommend SafeEyes <a href="https://slgobinath.github.io/SafeEyes/" rel="nofollow">https://slgobinath.github.io/SafeEyes/</a><p>While it doesn't detect video calls automatically, you can receive notifications and choose to skip breaks when needed.<p>More importantly, while it sometimes interrupts my flow, that also helps me reassess my current focus.
