Upload to a creative cloud library without the CC Desktop App?

Hi,

I am a newer Adobe Creative Cloud user here.   Recently, I created an Adobe Creative Cloud library and shared it with other colleagues.  The intent is for them to upload work-related photos into this Adobe library, and our company's media design interns could use the photos directly in a library in other Adobe applications like InDesign, AI, PS, etc. 

But, it seems that unless those colleagues have the Adobe Creative Cloud Desktop app installed, they cannot upload to a library.  Is there a way to upload directly to the assets.adobe.com library that I shared  without having the Adobe Creative Cloud Desktop app? 

Asking this question as we are not allowed administrative permissions on our work computers so having those colleagues go to the Adobe Creative Cloud Desktop app download site isn't an option.  In the meantime, we have reverted back to the "upload your photos to this SharePoint folder", but it doesn't make it streamlined for the media design interns to natively use with the InDesign Review Copy.  Perhaps there is a better way???
