How do I find the return type of the response from sharingGetSharedLinkMetadata

I'm using the javascript SDK to call the `sharingGetSharedLinkMetadata` API. This API might return either a SharingFileLinkMetadata, SharingFolderLinkMetadata, or SharingSharedLinkMetadata

Normally you would use the `.tag` field to see what type has been returned but that doesn't work in this case because SharingSharedLinkMetadata uses the same tag values as the other two.

So how can I find out which of these has been returned?

SharingFileLinkMetadata and SharingFolderLinkMetadata are each subtypes of SharingSharedLinkMetadata; they aren't three distinct types. So given a SharingSharedLinkMetadata, 'file' indicates a SharingFileLinkMetadata, and 'folder' indicates a SharingFolderLinkMetadata.

Aha! Thank you for this for insight - it makes more sense now.

However the way it's been done in typescript is that the API returns FileLinkMetadataReference | FolderLinkMetadataReference | SharedLinkMetadataReference

This means as far as typescript type checking is concerned, if I test that the tag is 'file', the type could still be FileLinkMetadataReference | SharedLinkMetadataReference so I get a warning if I try to access the 'size' poperty.

I've worked around it with casting but I think it would be better if the SharedLinkMetadataReference was removed from the API declaration - it's not needed because typescript already knows what the common fields are

Thanks for the feedback! I'll send this along to the team, but I can't promise if/when that change would be implemented.
