filter a Json by date in javascript

Question

I need to create the function that returns the expired boletos in relation to "data_expiration" and "30-07-2021" but I need to create this without changing the rest of the code beyond the existing function "filterSoultlyBoletosNoVencidos". I need to do this only by changing the previously created function. Someone can help me?

function buscaBoletos() {
  return [
    {
      "id": "1233559",
      "data_emissao": "2021-06-02",
      "data_vencimento": "2021-06-10",
      "valor_aberto": "89.90",
      "documento": "25523",
      "linha_digitavel": "23795246029000016306404004566909187180000007990",
