How can I connect nodes by C++ or Blueprint?

I’d like to construct a control rig blueprint by script.

Unreal Engine give us “Add Node function”, for example “Add Branch Node”. But I cant find a function for connecting those nodes.

Do you know how to connect those nodes by script?

Can you construct a control rig blueprint by C++ or Blueprint? Do you know below api?

Let me know when you construct a control rig blueprint by using those api. In real game development, most of the work is done by automation tools, not humans. Human’s work is developing automated tools.

(In addition, I solved it myself.)
