How to enable hints in the Google Maps API?

Question

Python

Hello, I connected Google maps to a jung project with the purchase of an API key. But I didn’t find where to turn on auto-suggestions of addresses, so that with partial input it would offer options. Also, the question is, for some reason, the view of the map is blurred, with a light translucent background, can someone know how to remove it? It is clear that this is configurable, just maybe someone has more experience and can tell you where to look.
