If you have created feedback as a file or as a video or piece of audio in OneDrive/Stream then you can link to that in MAF.
To add a file, in the markers editing page you have an option near the top in the blue box to choose a file
Click the choose file button, navigate to where the feedback is on your computer, select the file and upload it.
The file will then available for the student when they are looking at their feedback.
To add a link to audio/video feedback recording from OneDrive/Stream there is a space for the URL in the light yellow box between the upload documents box and the provisional marks box.
You will need to paste in a share link. To find out how to create these, check out our Sharing a OneDrive file or folder guide
Then in MAF, paste that URL directly into the OneDrive share URL box and click save.
