How to use node field tokens as a value in Metatags module? I am trying to optimise SEO on my site by ensuring that each page has a unique value for descriptive metatags.

I am trying to achieve this using the Token and Metatags modules, and am using Drupal 8.

To do this, I have added a field called "Description" to both the basic page and article content types.

I would then like to use the [node:field_description] token as the value for any relevant metatags in the Metatags module.

However, when I view available tokens in the Metatags module the [node] token is not available and the [current-page] token doesn't appear to have any way to reference the main node displayed within that page.

I know this issue has been discussed extensively for D7 and this issue appears to provide what I'm looking for:

Is there an equivalent solution for D8? Alternatively, what's the best way of achieving this?
This from Mario Steinitz (in comments) answered the question:

"I'm not at my desk anymore for today, but I'm pretty sure you have the [node] token available for content meta tags and can access field content as well. We're using these tokens regularly for all D8 sites we're working on. Where did you try to add them?"
