Trouble activating the bot

[Nyholm]

I've followed the instructions in the readme but the bot still does not make a comment on stale PR. Am I doing something wrong?

Here is the repo: https://github.com/thephpleague/fractal
Here is the config: https://github.com/thephpleague/fractal/blob/master/.github/stale.yml

The image below show that I've configured the app.
