2. In the QMC, click on Apps in the left pane and go to the Apps section.
3. Click on the Import button in the bottom pane.
4. Click on Choose File, select the application to be uploaded from your local folder, and press Import. Once imported, select the app and click Publish in the action bar.
5. You will be prompted to specify a stream for the application. Choose a stream from the defined streams in the drop-down menu.
6. Click on OK to publish.
