In Android, got click-jacked into clicking “Allow” for a pop-up that flashed for 0.1 seconds. How do I find out what I allowed?

In Android, I was using Google Chrome. I clicked on a sketchy website which popped up a new chrome tab. I pressed the tabs button which caused me to view the various tabs. Right as I was clicking on an "X" of the top-most tab, a pop-up appeared with the "Allow" button exactly under my index finger so I accidentally pressed "Allow". I had no idea what the pop-up said, except that there were two blue word buttons, and I clicked the right-most one. What did I accidentally allow and how do I disable it?
