How fx invocations work

Want to do an async task of adding two number together? Not problem.

invoke do/async-addition 40, 2
  # create a delegation for the result and get the CID
  result-cid = cid-for(delegate(do/async-addition-result 40, 2))

  # create a receipt for this invocation, including the CID of the result delegation
  receipt = generate-receipt-for(do/async-addition 40, 2, fx.join: result-cid)
