How can I create a sign-usdt transaction with javascript?

First I learned the Omni-Core and then the Omnicore-Cli, which can work
but I do not want to run a node on my local machine

=========================================

  1. Create a sign-usdt transaction
  2. Get the hex
  3. Transfer the hex using the API https://api.omniexplorer.info/v1/transaction/pushtx/

========================================

thanks for your thinking
