Beginner - what to do with last loop in project

I watched the video on binding off, but am at a loss of what to do with the last loop that is left on my needle to completely finish the project. Is there a special knot I need to use to finish it, or what?

Thanks!!

When you’re left with the last loop, cut your yarn and pull the loose end through the last loop and pull it tight. There’s a neat little trick to making that look as neat as possible, too, at the end of the video called ‘Demo of a Small Project’ on this page:
