What’s a Part? 

A element is a bundle that features a definition useful resource, written in markup, and will embody extra, optionally available sources like a controller, stylesheet, and so forth. 

A useful resource is type of like a file however saved in Salesforce somewhat than on a file system.

What you add to App Launcher is a Salesforce app, which wraps up an Aura element, one thing outlined in a <aura:element>. An Aura parts app—that’s, one thing outlined in a <aura:utility> —can’t be used to create Salesforce apps. A bit bizarre, however there it’s.
