Ah, I see-- you want notifications from this website. Got it.
FWIW I show the exact same setting but I have no memory of ever setting it one way or another. I just went into my Chrome settings (Settings - Advanced - Content settings - Notifications) and I actually have this site listed in the allow list (it’s the only one there beside the default Google account sites). Yet I never see desktop notifications from here (nor would I want to, I’m a minimalist in that regard, and don’t want anything nagging me about anything). So the site should not say I have permissions denied, yet it does.
So I got nothin’, sorry!
