If your interested in using onedrive to host models it can be done.
In firefox this is how I do it
select your model in onedrive
right click it then choose share one drive link
it will put the link ready to paste in a browser paste it and go to the download icon thing.
then right click it and down load it.
then in your downloaded files list right click it and choose “copy download link”
Then you will have the direct link ready to use in world.
Its a bit of a faff but works.
