Create connection between two points

I am creating a project that simulates a network that dynamically updates itself based on what node you are on. I am trying to create connections between nodes, which are actors of a blueprint class that I spawn. Is there a way to draw lines between these actors in blueprint? Currently I have vectors as to where the lines should start and end.

Perhaps https://www.youtube.com/watch?v=SccSLUk1l2A

I saw this video, but it does the connection in the editor not in blueprint.

I ended up using this tutorial: https://www.youtube.com/watch?v=ywd3lFOuMV8 which created lasers and then I changed the source and target attributes in blueprint.
