Embed Hub shows a Google Calendar, a Google Drive folder, a published Google Doc, Sheet or Slides file, a Google Form or a Calendly booking page on your site, inside a tidy frame that resizes for phones. Paste the link, or the whole embed code, and the app recognizes what it is, tells you in one plain sentence what must be switched on at the provider (for example a public calendar, a shared folder or Publish to web), and builds a safe address for you.
For calendars you choose the view (month, week or list of events), the day the week starts and the time zone, with US Eastern as the starting choice. For Drive folders you choose a list or big icons. Add a heading and a height to each item, show up to twelve items, and reorder them. An optional button can load an item only when the visitor clicks, and every item has an Open in a new tab link.
Place it inside a box you name or just above your footer, and limit it to chosen pages. Honest by design: it shows the provider's own page, so it cannot restyle it or make a private item public. Visitors connect to the provider when the frame loads, and the app collects nothing about them.
