Get most recently created list item with MS FLow

I am new to Flow and want to use it to retrieve a single list item and copy it’s contents to another list on a different site. I have found many guides explaining haw to retrieve all the items in a list but I only want the most recently created one (the item whose creation triggered the flow)

Can anyone suggest how to accomplish this in baby-steps as this is my first attempt at using Flow instead of SharePoint Workflows.
