How to get Kamenev/Zinoviev into power? Too stupid to understand path guide.

The path guide description is incomprehensible to me. I've tried multiple times, but I still haven't learned anything.

How do I prevent unity from being too high?

How do I make the leader less popular?

How do I manage the coalition?

How does the factionalism spirit change?

What does anything in the decision tab mean and how does it translate to the different words used in the path guide?

I have no clue what to do. I tried just agreeing with the communists on everything, but this just led to the socialists leaving and having full unity.

Just tell me briefly like I'm 4 how to get Zinoviev.
