Being new to SharePoint I am trying to create a form that displays on a page. I have access to SharePoint Designer and InfoPath. I do not have access to Power Apps or anything else. Ultimately the goal is to have the form gather information for campaign requests where these requests can later be approved/denied and the requester can go to another page to get Campaign Status information.
What are my options are for storing the form fill-in data in SharePoint and having the form display on the page without having the +add item button?
Example : user1 requests a campaign by filling out the form by going to a webpage with the form; manager1 goes in and requests/denies; user1 checks status of initial request.
Any info is helpful, keep in mind I am very new to SharePoint so details really do help.
