How do you open an MPKX file online?

[CP55]

I only have ArcGIS-Online, and am trying to open up a MPKX file.  I'm able to upload it successfully into the program, but when I try to open it it prompts me to open the desktop version, which I don't have. Is there a way to open this in the online only version?

While you can store many types of documents in ArcGIS Online, a MPKX file is an ArcGIS Pro map package that contains the map document and associated data. It cannot be opened directly in ArcGIS Online.
