Onedrive can’t backup iphone live photos

How to backup iphone live photos with Onedrive?

My photos are always in heic format. However, when auto-backup to Onedrive, it is ALWAYS converted to jpg format! 

This is making me mad. I have reinstalled onedrive several times and it doesnt work at all. There is also no option to choose uploading the photos in their original formats in Onedrive settings. 

I am using a university account. Does that affect anything?

thanks!!
