Multi Scroll widget missing live templates feature

Hi, I just purchased Multi Scroll from Code Canyon. On your website you give instructions and mention “You can use Elementor Live Templates feature to create/edit Elementor template on the same page” Here is screenshot from your website: https://imgur.com/a/FLMQa70
( from: https://premiumaddons.com/docs/multi-scroll-widget-tutorial/ )
Where is this button? I don’t see it. It appears on other Premium widgets I use, for example I can see it when I use the Modal Box widget. But it is missing from the Multi Scroll widget. Here is a screenshot showing the multi-scroll interface in the Elementor editor: https://imgur.com/a/Vnn0v7B

(please don’t ask for a URL because it isn’t relevant in this case)

Thanks and best regards
