Assigning the Follow target of vcam2d through code

How can I set a target in a 2d vcam (The Follow field) through code. It needs to be set at runtime since the player is not in the scene when the game starts and I can't find it in the API. The follow field to be none existant and I didn't find anything about it over the web.

??? = FindGameObjectWithTag("Player").transform;

What goes there with cinemachine? How can I set this at runtime for the Follow field in the 2d vcam?
