I need to install 2 Google Analytics counters to AMP pages. Can you tell me please if my code is correct?

<script async custom-element="amp-analytics"

<amp-analytics type="googleanalytics" id="analytics1">
<script type="application/json">

     "account": "UA-39707521-1"
     "account": "UA-75823543-3"
  },
"triggers": {
