How to use the @taquito/taquito.DEFAULT_FEE.DELEGATION function in @taquito/taquito

it('Simple set delegate', async (done) => {
      const delegate = 'tz1PirboZKFVqkfE45hVLpkpXaZtLk3mqC17'
      const op = await Tezos.contract.setDelegate({
        delegate,
        source: await Tezos.signer.publicKeyHash(),
        fee: DEFAULT_FEE.DELEGATION,
        gasLimit: DEFAULT_GAS_LIMIT.DELEGATION
      })
      await op.confirmation()
      expect(op.hash).toBeDefined();
      expect(op.includedInBlock).toBeLessThan(Number.POSITIVE_INFINITY)

      const account = await Tezos.rpc.getDelegate(await Tezos.signer.publicKeyHash())
      expect(account).toEqual(delegate)
      done();
    });
