About hiding the “Continue” button

Hi ARI soft team,

I previously purchased “Developer” from “ARI Stream Quiz”.

When I created “personality quizzes” with the plug-in and checked it, the “Continue” button was displayed after answering the question, and when I pressed the “Continue” button, the result was displayed.
Below are the WordPress versions and settings.

● WordPress version
5.3.2

● ARI stream quiz version
1.5.53

● “ARI Stream Quiz”> “Quizzes”> “Edit Quiz”> “Settings”

● The displayed “Continue” button
<button class="button button-green full-width button-complete-page">Continue</button>

In WordPress 5.6 and 5.7, even if you answered the question with the same settings, the “Continue” button was not displayed after answering, and the result was displayed.
I want to hide the “Continue” button even in WordPress 5.3.2. How should I set it?
We kindly ask for your confirmation.
