Chrome Address Bar API?

Question

Google Chrome

Good afternoon.
I decided to try to implement an extension for Chrome, but I have a question:
How can I interact with the address bar?
Where can you read about it?
Those. I want to implement an express panel that would appear when clicking on the address bar.
Actually make an analog like in Safari.
