Add HTML to radio button group [RESOLVED]

I am trying to add an HTML element to each radio button, just after each tag. So where a radio button renders as

<li class='gchoice_10_5_0'>
    <input name='input_5' type='radio' value='Item 1|10'  id='choice_10_5_0' tabindex='1' />
    <label for='choice_10_5_0' id='label_10_5_0'>First Choice</label>
</li>

I am trying to generate

<li class='gchoice_10_5_0'>
    <input name='input_5' type='radio' value='Item 1|10'  id='choice_10_5_0' tabindex='1' />
    <label for='choice_10_5_0' id='label_10_5_0'>First Choice</label>
    <div>New html here</div>
</li>

Any help would be appreciated.

So I was able to modify the form output by using the gform_field_choice_markup_pre_render filter as described in the [Gravity Forms documentation]
(gform_field_choice_markup_pre_render - Gravity Forms Documentation)

Here’s my code:

add_filter( 'gform_field_choice_markup_pre_render_4', function ( $choice_markup, $choice, $field, $value ) {
    if ( $field->get_input_type() == 'radio' && rgar( $choice, 'text' ) == 'Option 1' ) {
        $description = '<div>New html here</div>';
        return str_replace( "</label>", "</label>$description", $choice_markup );
    }

    return $choice_markup;
}, 10, 4 );
