How to use the @ffxiv-teamcraft/simulator.Buff.STEADY_HAND_II function in @ffxiv-teamcraft/simulator

return allsh2Indexes.some(sh2Index => {
      const actionsUsedWithSh2 = simulationResult.steps.slice(sh2Index, sh2Index + 5) || [];
      const clone = simulationResult.simulation.clone();
      clone.removeBuff(Buff.STEADY_HAND_II);
      const result = !actionsUsedWithSh2.some(step => step.action.getSuccessRate(clone) < 80);
      if (result) {
        this.matchingIndex = sh2Index;
      }
      return result;
    });
  }
