Continuing the discussion from [Getting joined data for widget scope](https://meta.discourse.org/t/getting-joined-data-for-widget-scope/42264/4):

I am trying to extend the `poster-name` widget and add some user custom fields next to a user’s name on a post.

As per @eviltrout:

> The poster-name widget has access to the entire post as attrs.

`whitelist_staff_user_custom_field("myCustomField")` in `plugin.rb` ✅

I have whitelisted the custom field I am trying to access but when I view `attrs.userCustomFields` of the `poster-name` widget it is undefined. Am I missing a step to make the user custom fields available to the widget/plugin?
