How to change the settings for a website?

After I add a website to Cliudflare it says “Review Settings”, 2 of 4 items complete. Please see the screenshot for one of the domain I have.

For one of the website, I have completely all 4 steps, but Now I need to Modify it, I could not find a menu item, which would allow me to change settings.
Please advise,

You can just find all the settings on the sidebar. That overlay is just for getting started.
