It is not possible to add a whole PowerPoint presentation to be presented in the learning page. However, we can add a URL directing to the PowerPoint presentation. In order to do that you have to follow the steps below:
Firstly, you have to upload the file in the library:
1. Access files in library and click on upload in the top right corner;
2. Add a tag for searching, upload your file, set the file name and check the box "public";
3. Click on upload;
4. Go back to the files' dashboard;
5. Search for your recently uploaded file and click on actions in the same row as your file;
6. Right click "open". You can copy the page URL which you'll paste as a URL in the Learning Page. If you click on pen, the PPT will get downloaded.
