Question:
How can we make connections in BPMN between the end points of one process and the starting points of another process?
Answer: Mavim sticks to the formal BPMN specification.
The formal definition of BPMN (the specification of BPMN by OMG) is:
- a Start-event in a Process cannot have an incoming event/sequence-flow; from a Task/Activity; Call Activity or (sub)Process.
- a Start-event can have an incoming Message-flow from another Pool/Process in the Collaboration.
- an End-Event in a Process cannot have an outgoing event/sequence-flow; to a Task/Activity; Call Activity or (sub)Process.
- And End-event can have an outgoing Message-flow to another Pool/Process in the Collaboration.

but ending it with a Call Activity;

calling some other external (sub)Process-B (an external Orchestration or Collaboration).

However; in the chart of the called external Topic (Process-B); you will not see in that chart that it’s started from within another (external) Topic (Process-A).
Or you can visualize in the Collaboration of Process-B that it starts from another Pool/Process (Process-A); via a Message-flow from Pool/Process-A to Pool/Process-B (or activities within).
