Apple Pre-Order review

I have been working on a mobile app that I would like to upload on Apple console - pre order. The criteria for this is pretty much unclear. My team wants to use this pre order link for marketing, now I would like to know if I can publish a unfinished app on pre order to use it as marketing and then upload the completed app once we want to go live.

Please explain what should be the criteria, also can the app be uploaded it we only have the completed front-end
