+The function should return a boolean value. True if the drop was handled by the hook and futher native processing should be stopped, and false if Excalidraw should continue with the processing of the drop.
+type of drop can be one of:
+- "file" if a file from Obsidian file explorer is dropped onto Excalidraw. In this case payload.files will contain the list of files dropped.
+- "text" if a link (e.g. url, or wiki link) or other text is dropped. In this case payload.text will contain the received string
+- "unknown" if Excalidraw plugin does not recognize the type of dropped object. In this case you can use React.DragEvent to analysed the dropped object.
+
+Use Templater startup templates or similar to set the Hook function.
