Not required here as you are initializing in `createAndShowUI` method.

This condition is not satisfied and hence the test failed in win11 machine. In linux machine, once the current directory is at `root` then pressing the backspace key doesn't have any effect.
But looks like it is different in windows and mac. Checked in windows native explorer, once it reached to `home` folder, it toggles between `home` and `Desktop` on backspace key press. The condition checked here will never satisfy and `passed_2` variable remains false.

So, either you can check the condition differently or may remove this check for windows and mac.
