When does an Addon go public

If my Addon is approved by code review, does it immediately go to the public or can I determine when it goes public?

If you upload a listed extension version it will be available pretty quickly once the automated checks approve the extension. So it’s not quite immediate, but there is also no more manual step.

If you mark it as Experimental, it will have reduced visibility on AMO. For example, it might not come up in searches.
