Revise a published dashboard on grafana.com

How do I publish a revision of one of my dashboards on grafana.com? All I can see is how to upload a new dashboard, but I don’t see how to do a revision of an existing one.

View a dashboard under your user/org owner and switch to Revisions, e.g.

Thank you. I got it now. Somehow the browser was juggling with two different accounts and didn’t show me that [Upload revision] button.
