Apple Pencil Not Drawing

Okay, I feel like I must be a big dummy. My Apple Pencil finally arrived today at long last. I plugged it into my iPad Pro to pair it via bluetooth. I checked the battery charge in the Today View, and it says 100%. When I open my Notes App and try to write, it acts like a styus - I can click on keyboard keys and get the zoom bubble if I hold it down, and I can move the page around by holding the pencil on the page and moving it. But, I cannot get the dang thing to make a line or write anything.

Someone in another post suggested to make sure the tip was screwed in all the way. Did that. It did come with an extra tip - was I supposed to use that? Is there something I am supposed to choose in a menu somewhere to activate the pencil or "tell" iPad Pro I want to use the pencil as a writing tool? I'm confused. I must be getting old because I used to use the new products with ease...

Help?
