Set dropdown select by value

Question

Is it possible to set selected specific item of dropdown in Google apps script (Gmail add-on) from the action?

Example: I have one dropdown with 5 items (10, 20, 30, 40, 50) and one button. Default selected item of dropdown is 10 (dropdown.AddItem(10, 10, true)). When I click button I want to change selected item of dropdown to 40. Is it possible to do?

UPDATED:

function onHomepage(e) {
  var max = CardService.newSelectionInput()
      .setType(CardService.SelectionInputType.DROPDOWN)
      .setTitle('Max')
      .setFieldName('max_field')
      .setOnChangeAction(CardService.newAction()
        .setFunctionName('maxHandler'));  

  for (let i = 10; i <= 100; i += 10) {
    var selected = false;
    if (i === 10)
      selected = true;
    max.addItem(i + "$", i, selected);
  }

  var _btn = CardService.newTextButton()
      .setText('Button')
      .setTextButtonStyle(CardService.TextButtonStyle.FILLED)
      .setOnClickAction(CardService.newAction()
        .setFunctionName('btnClicked'));

  var btn = CardService.newButtonSet()
      .addButton(_btn);  

  var section = CardService.newCardSection()
    .addWidget(max)
    .addWidget(btn);

  return CardService.newCardBuilder()
    .setName('cardName')
    .addSection(section)
    .build();
}

function btnClicked(e) {
  var selectedMax = e.formInput.max_field;
  console.log(selectedMax);
