如何在运行时更改aTradingView Widget的符号名称?

I am creating an android application which has a web view which implements Tradingview widgets. But the problem is when the widgets will open in my application, the user will not be able to change the symbol name of that widget. Currently, the widget shows the data which was created using Embed Code which is present on Tradingview website. The widget should show the data of a symbol which was entered by the user at runtime. please help me to how to do that.

  <!-- TradingView Widget BEGIN -->
 <div class="tradingview-widget-container">
 <div class="tradingview-widget-container__widget"></div>
  <div class="tradingview-widget-copyright"><a 
  href="https://in.tradingview.com/symbols/BSE-DABUR/technicals/" 
  rel="noopener" target="_blank"><span class="blue-text">Technical 
  Analysis for DABUR</span></a> by TradingView</div>
  <script type="text/javascript" 
  src="https://s3.tradingview.com/external-embedding/embed-widget- 
  technical-analysis.js" async>
  {
   "showIntervalTabs": true,
   "width": 425,
  "colorTheme": "light",
  "isTransparent": false,
   "locale": "in",
   "symbol": "BSE:DABUR",
  " interval": "1m",
  "height": 450
  }
  </script>
  </div>
   <!-- TradingView Widget END -->

The above code is generated by the TradingView website. I want to change the "symbol" value which will be entered by a user at run time.
