Hi
I use Things app for my Todos. So I have a link in the description of a card like
things:///show?id=9z65rLcRjbjNjF46orDcsZ
If I click the link I get the dialog 
If I click 'Proceed' it opens in the Things app correctly.
The issue is this message comes up every time I click on it. This is annoying as its now 3 clicks: one click to open the card, one click on the link and one click on this message.
Ideally I'd like to click the Cover image or Description on the closed card and be taken to Things.
I've looked in Security & Privacy in System Settings, but cant see anything to tweak.
I'm (still) on Mac OS 10.15.7.
Anything else to try ?
thanks
