How do i hide password field in google datastudio appscript?

I am making a datastudio appscript connector. The user has to provide a username and a password but the passwrod is visible when he is typing in the input field. How do i hide it. Ive tried looking in the document but did not found anything.

var cc = DataStudioApp.createCommunityConnector();
var fields = cc.getFields();
var types = cc.FieldType;
var aggregations = cc.AggregationType;


  config
    .newTextInput()
    .setId('uname')
    .setName('username')
    .setHelpText('Your Database username')
    .setPlaceholder('Enter username')

  config
  .newTextInput() // I want to hide this field
  .setId('pass')
  .setName('pass')
  .setHelpText('Your Database Password')
  .setPlaceholder('Enter Password')

Solution

As of this writing (July 2021), the TextInput widget does not currently support hidden characters. This has been reported on Google's Issue Tracker:

If you really want Google to prioritize this issue make sure to star it (commenting alone has little to no impact, its the star count that matters).
