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

const usedManipulationTooEarly = manipulationIndexes.some((index) => {
      const repairSteps = simulationResult.steps.slice(index + 1, index + 1 + new Manipulation().getDuration(simulationResult.simulation));
      const matches = repairSteps.some(step => {
        return step.afterBuffTick.solidityDifference === 0 && step.solidityDifference === 0;
      });
      if (matches) {
        this.matchingIndex = index + 1;
      }
      return matches;
    });
