Folder undelete after real time sync deletion

Is it possible to recover a folder online after it has been deleted by a real time synchronization deletion? When the folder was deleted from my local drive it was also deleted from online storage since it was real time synchronized. Now I cannot recover it from my local drive. Is it possible to recover the online copy?

Added comment: There’s nothing in the recycle bin online.

Unfortunately no, it’s not possible.
Once a file/folder is deleted it’s not recoverable.
