How do I turn on Bullet Time mode? (Cyberpunk 2077)

Hello everyone!
Guys, what needs to be pumped in order to enable the Bullet Time time dilation effect during shootouts? I have already played 20 hours, but I haven’t entered how to install this function (

And then, how skills are pumped, for example, the skill "strength" I still have level 5, and in many things, level 6 is very useful. purchases for points of everything that is open in the corresponding section? And I thought it is pumped automatically as you receive points for completing missions, for fights, etc. But the campaign is not, and remained at this level
