NO:32 HOTSPOTA user is creating their first canvas app in Power Apps.

Box 1: Gallery

A Gallery control can show multiple records from a data source, and each record can contain multiple types of data. For example, a Gallery control can show multiple contacts with each item showing contact information that includes a name, an address, and a phone number for each contact.

Box 2: Meeting-screen template

In a canvas app, add a meeting screen that lets users create and send meeting requests from their Office 365 Outlook accounts. Users can search for attendees in their org and add external email addresses. If your tenant has meeting rooms built into Outlook, users can select a location as well.

Box 3: Image

If you add one or more Image controls to your app, you can show individual images that aren't part of a data set, or you can incorporate images from records in data sources.
