Dark Mode doesn't automatically activate based upon the DE's colouration.

Expected Behavior

I expect Proton Bridge to adhere to my DE's colouration. This applies to at least Windows 10, Windows 11, KDE Plasma 5, KDE Plasma 6, and GNOME 30 and GNOME 40.

Possible Solution

Adhere to it.

Steps to Reproduce

#!/usr/bin/env -S pwsh

#```PS1
#Requires -PSEdition 'Core'
#```

Get-Command -Name 'protonmail-bridge'
If ($? -Eq $True) {& protonmail-bridge}
If ("$Env:XDG_CURRENT_DESKTOP" -Eq "KDE") {
    If (lookandfeeltool --list | Select-String -Pattern 'org.kde.breezedark.desktop') {
        lookandfeeltool --apply 'org.kde.breezedark.desktop'
    }
}

Current Behavior

Notice how it remains white?

Context (Environment)

I have to manually change the theme in the application every time I access it, because my DE automatically switches between dark and light themes based upon local sunset/sunrise times (I use https://github.com/oskarsh/Yin-Yang/releases/tag/v3.4).

Detailed Description

Merely change the boolean value currently set by that toggle in the GUI based upon the undermentioned.

Possible Implementation

The current theme is probably exposed via DBus, so you can wait for a command from there, rather than constantly poll for the current theme.
