[how to edit "request" ?]

Hi, first message here. Just joined to Fiverr to post some jobs, and currently trying to figure out basics. I quickly prepared a request, and post it (assuming its same thing as 'job' on some other platforms).
Now I want to edit it, but could not find any function/menu to edit a posted 'request'. According to web sources, there should be a 'dashboard' menu, not available anywhere.

And now I am seeing theres an "orders", to further complicate things. And yes, its not visible anywhere, either.

Is there any how-to page for Fiverr ?

Thanks for the answers!
