How to access Shopify's built in metaobject attributes? date added, created, etc.

Hello, I have a metaobject which essentially mimics blogs (along with other features). I would like to utilize information that shopify tracks

For metaobjects, I know that Shopify tracks update and creation date on their end, as well as who created each object (author).

But for some reason I am unable to utilize this information within, lets say, a liquid template.

for example, none of the following


{% assign featured_metaobjects = metaobjects | where: 'is_featured', true %}

{% for recipe infeatured_metaobjects limit: section.settings.post_limit %}

<p>Author: {{ recipe.created_by }}</p>
<p>Author: {{ recipe.createdBy }}</p>
<p>Author: {{ recipe.created_by.value }}</p>
<p>Author: {{ recipe.createdBy.value }}</p>

<p>Date{{ recipe.created_at | date: '%Y-%m-%d' }}</p>
<p>Date: {{ recipe.createdAt | date: '%Y-%m-%d' }}</p>
<p>Date: {{ recipe.created_at.value | date: '%Y-%m-%d' }}</p>
<p>Date: {{ recipe.createdAt.value | date: '%Y-%m-%d' }}</p>

{% endfor %}

Please help
