Possibility to Inject an html element inside Form?

I am trying to inject an Html element just after the input field in the form widget. Let's say I want to put an eye Icon after Password field. I could be able to put it before field group but didn't find any filter to put it after or before inputs.

My current hacky solution is to create another field group(label, input or anything else) and setting style display:none to the old one.

If there is no such filter, is there any method to remove the field. May be something like `$form_widget->remove_render_element()`

It could be done using Javascript though. But I don't want make an extra request for that.

```php

// Password Preview Icon
if( $field['password_preview_toggle'] === 'yes' && $field['field_type'] === 'password' ){
$print_label = ! in_array( $field['field_type'], [ 'hidden', 'html', 'step' ], true );
?>
