Added Extension....now what?

I’ve already added the extension to my Chrome. Oh, now what do I do? Because it’s not saying anything has changed. And it doesn’t give me any information about what to do after. Then again, I’m not very tech-savvy so. If someone can please help me. I really appreciate it.!
