Is there a way to make Linux Mint switch power mode automatically on laptops?

Is there a way to make Linux Mint on my laptop switch power modes automatically between Power Saver and Performance whenever I plug/unplug my laptop?

It already does that behind the scenes

the kernel automatically sets a higher power profile (enery_performance_preference) when plugged in and resets it when unplugged

the UI just doesn't reflect the change

How do I tell it's doing that behind the scenes?

cat /sys/devices/system/cpu/cpu*/cpufreq/energy_performance_preference outputs balance_performance or performance

[upbeat swallow]

can also be done from terminal or bash script:echo "performance" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

cat that file to see the current one per core
