Does the Torah scroll belong to the Jews or to the Polish community where the Jews used to live, but were killed/expelled?

That’s like asking do we return historic relics found in modern Turkey made by Greeks or Armenians to Greece or Armenia since there are no more Armenians and Greeks living in Turkey or do they go to a Turkish museum?

Is there a Polish museum dedicated to Jewish life in Poland? Or they can be donated to still active Polish synagogues or to a holocaust museum.
