Push in Safari dosen't work?

I have Webpushr on my WordPress-side with the plugin activated and it works perfectly with Chrome.
Today I got an Apple Developer license to activate push notifications in Safari on Mac.
When browsing the site alexed.se I’m getting the question to activate push notifications. When doing so the site won’t show up in the notification menu over websites in settings, nor does it deliver notifications in Safari (didn’t get the welcome push or a push from a new post).
I have activated notifications in settings in Safari and System preference. But nothing happens.
Does anyone know if it’s a Webpushr bug when it comes to activate in Safari or just if it’s Safari that does’t really work at the moment with push messages?
Thank you.
