How to use the next MagicaCloth2 API Code?

Hello everyone, I’m working with the MagicaCloth2 addon, nice stuff to make cloth simulation, I currently want to automate the creation of the MagicaCloth Component because we’re often do some changes in the mesh, so I have a lot of parameters that I really want just to copy to the new model, the documentation provide me the next code from the API section:

/// <summary>
/// パラメータをJsonへエクスポートする
/// Export parameters to Json.
/// </summary>
/// <returns></returns>
public string ExportJson()

and

/// <summary>
/// パラメータをJsonからインポートする
/// Parameterブロックの値型のみがインポートされる
/// Import parameters from Json.
/// Only value types of Parameter blocks are imported.
/// </summary>
/// <param name="json"></param>
/// <returns></returns>
public bool ImportJson(string json)

but due to my lack of skills on code, I have no clue how to how to assemble this, any hints or help?
