How do I select only the unwelded edges (seams) of a mesh?

Is there some built-in or plugin component that can select these mesh edges that are highlighted with thicker lines?

There’s a component called MEdges (Mesh Edges). It outputs the naked edges (E1), interior edges (E2), and non-manifold edged (E3), if there are any.

The problem is that neither of these outputs gives me only the unwelded edges (displayed in thicker lines).

There are no non-manifold edged in this wesh, and no naked edges either, so I just get all the edges in the mesh form (E2), when I only need some of them.

So to see the unwelded edges, one does this?

Or more directly, this:
