Move emails to folders?

Hi all. Is there an option to move emails from the inbox into folders, e.g. to spam or into any other folder?

On the top right there should be a three-dots-button that should lead to a “refile/move” menu point.


But “refile/move” seems to only allow mail to go to other top level folders (e.g. Spam, Trash etc.) not to sub-folders of the Inbox. What am I missing?
