Downloaded mobile app - how to create folders IN MOBILE

I searched the help folder and the mobile help page but believe it or not, the help I need is more basic than what they cover. I am not planning on using Obsidian on a pc or laptop, ONLY MOBILE. I’ve created a couple notes but how do you create a folder? I have poked around and all I see is ‘search’ , Aa, a search option slider icon, and on the bottom it says ‘Main/2 files, 1 folder’ with a down arrow and when I click that it says Main is checked, and there’s a ‘Manage vaults’ option. Settings doesn’t contain anything that says or indicates ‘create folder.’ Your help is appreciated in advance.

What I’m trying to do
