hyperlink – How to make a dynamic PDF viewer in isolated page? SharePoint 365

I need to make a page for my company where we will show the daily report. The page must be updated daily and maintain the same access link. In the page we want to show a PDF through a PDF viewer. The page will be accessible for people outside of my company, and must not have pathways to other pages, I think I can control that through permissions and not showing links.

How can I do this in SharePoint?
Do you have any sugestions?
