TOTP with KeePassXC

I have been using Authy but with the latest news that they will retire the desktop app, I’m looking for something else.
Now I was giving KeepassXC a run, which also is able to generate totp’s but it doesn’t work.

I tried 2 different ways:

  • scan the QR-code with ShareX
  • manually copied the code

Is it not possible to use KeePassXC and if so, why is that?
