Implement Continuity Markup in Mac app?

Hello,

is there a way to implement Continuity Markup in our own apps?
(This is what I'm talking about: https://support.apple.com/en-us/102269 , scroll down to "Use Continuity Markup").

Also, why does a QuickLook panel (QLPreviewPanel.shared()) not display the markup options when triggered from my app for png image files in my app's Group Container? Do I need to implement certain NSServicesMenuRequestor methods for that?
Sadly, I could not find any docs on that.

Thank you,
– Matthias
