+`plugin-playground:share-via-link` shares a file or folder. If no `path` is
+provided, it shares the active file. The file/folder right-click context-menu
+entries use the selected browser item path automatically.
+Folder sharing skips non-text/media files (for example images and videos).
+By default, folder sharing always opens a file-selection dialog so you can
+exclude files before creating the link. You can control this with
+`shareFolderSelectionDialogMode` (`always`, `auto-excluded-or-limit`, or
+`limit-only`). If the generated URL is too long, you can pick a smaller subset
+of files in the same dialog.
 The same action is also available from the `IPluginPlayground` API via
 `shareViaLink(path?)`.
 
-When opening a shared URL, Plugin Playground restores and opens the shared
