Wiring a Shelly (1 or 1L) for a porcelain pull cord light fixture?

I have got an old porcelain pull cord light fixture in my basement that needs replacing.

I am thinking about implementing button on the wall to turn the light on and off. I have the on hand:

• Replacement porcelain pull cord light fixture
• Shelly 1
• Shelly 1L
• Shelly bridge
• Shelly button (actually not on hand yet, but arriving in the mail soon)
• Tools for electrical work

Do I need to use the Shelly 1L or can I use the Shelly 1? Does anyone have something like this in place with a Shelly device? Anyone have a quick diagram they can share?

Also, I am assuming I need to test for which wire is the hot wire and which is the neutral as I am guessing both wires are black (which I keep finding in my 1890's house that has at least had the knob and tube wires replaced before I moved in).

FYI - I realize I could have replaced the light fixture with a number of other solutions, but I had not planned on connecting this to my home automation system until my wife asked about wiring for a switch and the only thing I did not have on hand was the Shelly button and a sample wiring diagram; hence, this post (plus the Shelly button seems cool to me )

Here are some pictures for reference of the type of light fixture I am working with:

Which of these diagrams is recommended for my specific setup that is detailed above? Or was this an automated post to the forum using the word "diagram" as an automated trigger for the message?

I see. Thank you. (Poor joke on my part about the "automation" I have some questions about those diagrams. I think I need to go with the Shelly 1L because there is no neutral wire. But all of the diagrams show either multiple switches for one bulb or multiple bulbs for one switch. I have one switch (pull cord) and one bulb. Are there diagrams in Shelly support for a simpler set up (or a simpler user ) I have wired a few home automation devices in my home and bought the Shelly devices hoping they would be good solutions for a number of use cases. Also, I was hoping there might be a lot of people using them in many situations. I have seen some good communities of users that like to share and help.
