Service on Big Sur to start Terminal doesn't work with Finder, works with other apps I picked up a new MacBook recently and started customizing it software-wise.
After some research, I have managed to set a shortcut for opening Terminal as follows:

Open Automator
Select New Document, Quick Action, search „Launch Application“ and drag it over
Select the desired application (may be located in „others“)
Select File-&gt;Save in the menu bar
Open System Preferences and select Keyboard &gt; Shortcuts &gt; Services
Provide a shortcut for the Quick Action. In my case, I have selected CommandControlT

Sadly, the shortcut CommandControlT doesn't work when the Finder is the active app. With any other app, it works.
I don't understand why, as the shortcut isn't assigned to any action in the Finder.
Thanks in advance
There is default shortcut which may interfere: Mac keyboard shortcuts &gt; Finder and system shortcuts:

Control-Command-T: Add the selected item to the sidebar (OS X
Mavericks or later).
