Processing Content In Enclosed Shortcode

I am using a shortcode to quickly display user meta across text on my site. An example is [first_name] to display a registered user’s first name. However, while using the enclosing shortcode [content_control], the shortcode within an enclosed shortcode content is not processed.

For example, the [first_name] shortcode will not be processed:
[content_control]Hello [first_name]! How are you?[/content_control]

I have tried to add this to the plugin, but was not successful: https://developer.ww.wp.xz.cn/plugins/shortcodes/enclosing-shortcodes/#shortcode-ception
