Magazine grid within a static home page

In the old thread, I asked:

“The default post display on my homepage is the latest post. So all posts display in one column, with the featured image on the left side and the post titles on the right side.

However, I want to change to layout showing in demo version of the free Poseidon. That is, one post in the left column, and the rest on the right column. So I see there is a magazine widget in that kind of layout and add to the page. But how do I delete the default one to make the page like the demo Poseidon?”

The answer is to use a static home page. Yes, I can change to a static page now. But how do I add the Magazine Widget to the static home page? I read the document and still don’t understand how as the description is unclear to me.
On a static home page, I cannot find a place to add a magazine grid to include my posts.

What I want is to have the looking like the Demo version. Further helps would be aprreciated. Tahnks.
