Please add parent_id to the Meta

Please add parent_id to the Meta information.

Including parent_id in FileMetadata/FolderMetadata/deletedMetadata would make it easier to manage within the app.

When maintaining the Meta DB within the app and handling changes made via the /list_folder/continue request, including parent id information would also make it easier to handle changes or moves.

If only the path is provided, it's difficult to determine whether the folder is a deleted and then added folder with the same name.

I previously suggested that deletedMetadata require id information.

Thank you
