Unity Engine

how would i change what the cinimachine camera is looking at using a script? i need it to move from one section to another when a player hits a trigger box but i dont know how to change what its looking at from within a script.

// CinemachineVirtualCamera vcam
vcam.m_Follow = newFollowTransform;  // Determines the position of your vcam
vcam.m_LookAt = newLookAtTransform;  // Determines the rotation of your vcam
