Microsoft 365 allows users to create files only in the cloud, which would result only in a .lnk file locally.

LNK is a file extension for a shortcut file used by Microsoft Windows to point to an executable file. LNK stands for LiNK. Shortcut files are used as a direct link to an executable file, instead of having to navigate to the executable..

LNK files use a curled arrow to indicate they are shortcuts, and the file extension is hidden (even after disabling “Hide Extensions for Known File Types” in Windows Explorer).
