Are Push notifications ads Safe with Adsense?

I'm willing to try to boost my blog income using PropellerAds Push Notifications Ads.
Does that violate Adsense policies?
Since it looks like a push popup on mobile (kind of blocking access to the site content, until allowing or declining notifications)

Is that safe?
Or have anyone tried it?
