I watched a couple or so videos and it seems that it's all hardcoded, so while I can easily build a widget to look like its pulling data from the posts, it really is not, I just had to fill in all the data manually, so it's pretty much akin to adding a HTML block in Elementor and past the code in there. Or so it seems in your videos.

So the question is, can I add a widget that looks like.
<div class="me-class">
<img class="myclass" src="{var-post-featured-img}">
<h2 class="myclass" >{var-pull-post-tile}</h2>
<p class="myclass" >{var-intro-text}</h2>
<a class="myclass" href="{var-post-link}">{var-pull-post-tile}</a>
</div>

And that I can then set other variables, like setting it to PULL X posts, by ORDER.
