how to see toolbar in iCloud

I'm new to iCloud on my iMac. I don't see any toolbar when I'm logged in to my iCloud account. I've tried several browsers (firefox, chrome, safari) and I don't see any toolbar anywhere on the screen. I'm running IOS 13.2 on an Apple M1 2021. For example, I'm hoping to delete a file but the online guide says to drag the item to the "trashcan" icon on the toolbar.. there is NO TOOLBAR visible so this is impossible.
