Where are the files in Sketchup Web? can't export

Everything I read says Files Export STL. Great I understand that help. But there are no file menus. I’ve made two models and saved them. I want to print them on 3d printer. I need to export the STL data. Stuck at step 0.

Sketchup web is different from the desktop version and is changing all the time so some things you read may not be correct or current.
To obtain a .stl file from web simply click the hamburger menu, three lines top left of the screen, move to download and select .stl.

It was the answer. Not where I expect to find it. depends on your definition of ‘download.’ Thanks.
