Hi @thaxam,
Thanks for reaching out to us!
I can understand your query. Please be informed that the Widgets of the ShopEngine plugin can only be accessed and used through the ShopEngine Templates. For your information, each of the Templates that are created with ShopEngine will only show their related Widgets. Only the ShopEngine Product Archive and ShopEngine General are Global widgets that will always be displayed on the Widget area of Elementor Editor and you can use those widgets on any of the pages you want.
In conclusion, you will not be able to access all of the widgets from a Single Template. Each template holds specific widgets. So please create templates by navigating to ShopEngine > Builder Templates to experience how each widget works! I hope you can understand the matter now.
Let me know if there are any further queries or clarifications required.
Best Regards
Prosenjit
