Open BPM diagram from NWDI

Hi,

I succesfully connected to an NWDI track, and I can see all development objects there. I want to open an existing BPM diagram and edit this. I can create new DCs on the track, and edit them later on. However, BPM diagrams created by other people can't be accessed.

How can I open BPM diagrams that are already on the NWDI track?

Thanks!
