Visually appealing sockets

I greet you

I will have a kitchen island in my new kitchen.
This island has a beautiful stone countertop, and
the sides (panels) are made of the same material.

Now I would like to install one or two sockets on both sides in these panels. Of course, I could also take the sockets we have everywhere else. But I would not like them visually at all.

I am thinking rather of sockets that might be black and flush-mounted and that visually, if possible, consist only of the area where you actually plug in the plug. So no frames, etc.

Does anyone have a suitable idea here?

A couple of suggestions for you:

Merten M-plan
Gira E22

Both are quite flat, but still require a square recess in the brick!

Only round and small, I can’t think of anything.
