I shared a folder with another MS account of mine, and the shared folder opens up in the Shared section of OneDrive through the browser. When I do it with the directory in File explorer, it doesn't show up. I looked it up, and most of them tell me to sync the folder. So, I opened up the folder, and there is no sync button. Is there a way to make the sync button come back up? I need it since I am working with others on files that can only be opened with desktop grade applications.
