You have to use a kind of work around. This is one case that page builders or other systems that can generate shortcodes is helpful. You can nest a widget shortcode in an RC restrict shortcode. For example, I made an Elementor template that includes the WordPress widget to get an Elementor shortcode. Next I posted the shortcode on a test page. Next I wrapped the shortcode in an RC restrict shortcode to hide it.
Below is an example bit of code:
[restrict subscription=2][elementor-template id=”2574″][/restrict]
The elementor-template is a WordPress menu widget. I wrapped it in a restrict shortcode that only allows Members with the Gold pan that has an ID code of “2” to be able to see the widget.
This post, down near the bottom shows various options for use of the restrict shortcode: https://restrictcontentpro.com/knowledgebase/restricting-post-and-page-content/
