how to connect materials from .fbx file for rendering?

Hello everyone!
Guys, I urgently need help. There was work for an advertising agency (finally! Damn the COVID-19). It was necessary to make a model of glasses and I did.
.. That's just painted in Substance Painter.

Now they want me to render 360 degrees. But in the blender I only rendered a rocket from the tutorial. Please tell me how to connect a normal map and make opacity on the lens (it is in the alpha-channel of the BaseColor map).
I would be very grateful if someone could help.
