How to focus on a modal form using Bootstrap?

Question

JavaScript

Hello!
There is a modal window with a form using Bootstrap. It is necessary to focus on the form every time the modal window is opened without reloading the page.
Added "autofocus" attribute to "input". But focusing happens only after page reload.
And, JS - settings:
$('#myModal_1').modal({
focus: true
});
opens a modal window immediately upon initialization.
Thank you!

The very first example in the modal documentation is just for you https://getbootstrap.com/docs/4.0/components/modal/

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').trigger('focus')
});
