Link a Agenda Project/Note to open from another Project/Note

I am trying to link an existing project to another project/note so I don’t have 2 to maintain. I copied and pasted the Agenda note link in the new note but the link doesn’t open the other project. What am I missing?

Is there any chance you afterwards moved the linked note to another project? At this moment moving a note breaks the links unfortunately. If not, can you send a quick screen capture or some screenshots illustrating the steps you took?
