Attachments control in Power Apps
A control that allows users to download files to their device, as well as upload and delete files from a SharePoint list or a Common Data Service entity.
The attachment control has these limitations:
Attachments are supported with SharePoint lists and Common Data Service entities.
Upload and delete functionality work only inside a form. The Attachment control appears disabled when in Edit mode and not inside a form. To save file additions and deletions, the app user must save the form. Because of this limitation, the Attachment control isn't available from the Insert tab but appears in the form when the Attachment form field is enabled in a SharePoint or Common Data Service form.
You can upload files only if they're 10 MB or smaller.
An Attachments control lets you open, add, and delete files from a SharePoint list or a Common Data Service entity.

Create an app from data using a SharePoint list as a data source. As an alternative, add a form to your app, and set a SharePoint list as its data source.
Select the Form control in the tree view on the left-hand side.
Click Data in the Properties tab in the options panel on the right.
Under Fields, enable the Attachments field.
The Attachments field associated with the SharePoint list will appear in the form.
