Cannot access OneDrive on iPad

I have searched this forum and the web.  Many posts dated 2016 talk about Adobe adding support for OneDrive.  They reference using the Location Chooser to add OneDrive.  The screenshots from back then do not correspond to the product now.  I cannot find location chooser.  If I go to files, I see options; (1) On this iPad, (2) Document Cloud, (3) Dropbox, (4) ... More Locations.  If I use More Locationshis simply takes me to an iCloud window.

There is no option to add OneDrive.  How do I add OneDrive support?  It isn't a useful product without this support.

Thanks.
