Marketplace Project files Link question

Hello I am trying to figure out if this is a first time thing or how a submission is supposed to work, I got my project ready to go and got all the way to the version section of the submission and it says “Project File Link”, now how is this supposed to work ? If I fork out some cash for a box to host this pack I know better that leaving it unpassword protected etc so how is it supposed to be downloadable for the market place review team? Am I missing something? And do I need to do this for every product?

Found my own answer on Youtube, guess I have to stand up a box
