Remove OK button from kartik-v custom dialog - twitter-bootstrap-3

Question

I tried to create a custom dialog using yii2-dialog, one of the kartik-v widgets. I want to create this dialog with a single button: Statistics so, using the documentation provided in the demo, I wrote the code below.
The problem is that the dialog I get has two buttons instead of one and I CAN NOT get rid of the OK button.
My questions are: is there any way to create a custom dialog using yii2-dialog with a single button? and if possible, how can I achieve this?
use kartik\dialog\Dialog;
use yii\web\JsExpression;
echo Dialog::widget([
'libName' => 'krajeeDialogCust',
'overrideYiiConfirm' => false,
'options' => [
'size' => Dialog::SIZE_LARGE,
'type' => Dialog::TYPE_SUCCESS,
'title' => 'My Dialog',
'message' => 'This is an entirely customized bootstrap dialog from scratch.',
'buttons' => [
[
'id' => 'cust-btn-1',
'label' => 'Statistics',
'action' => new JsExpression("function(dialog) {
dialog.setTitle('Title 1');
dialog.setMessage('This is a custom message for button number 1');
}")
],
]
]
]);
// button for testing the custom krajee dialog box
echo '<button type="button" id="btn-custom" class="btn btn-success">Custom Dialog</button>';
// javascript for triggering the dialogs
$js = <<< JS
$("#btn-custom").on("click", function() {
krajeeDialogCust.dialog(
"Welcome to a customized Krajee Dialog! Click the close icon on the top right to exit.",
function(result) {
// do something
}
);
});
JS;
// register your javascript
$this->registerJs($js);
And this is what I'm getting:

You need to use dialogDefaults option, according to the docs the configuration options to be setup as defaults for the bootstrap dialog (applicable when useNative is false). and the default value for useNative is false until you explicitly set to true.
Update your Dialog definition to below and override the buttons property in the dialogDefault option as the plugin sets the ok and cancel buttons by default.
echo Dialog::widget ( [
'libName' => 'krajeeDialogCust' ,
'overrideYiiConfirm' => false ,
'dialogDefaults' => [
Dialog::DIALOG_OTHER => [
'buttons' => ''
]
] ,
