  /*
  * 2、

  * !!attention:
  *    create icsp use the balance of subAccount
  *    topup up use the balance of xtc ,So you should prepare enough xtc in principal in advance（principal not the subAccount）
  *
  * Best Practices:
  *    Add icp to subAccount to create icsp（maybe 0.2 icp）
  *    Use https://app.sonic.ooo/swap to exchange cheap xtc for plug wallet（1 icp ≈ 15.7 xtc）
  *
  * then call this function to create icsp.
