After 9 hours straight before the laptop, sometimes my vision blurs everything burning in the background and focuses on the poor fly trying to escape the window.
I need some sort of a brain horn TO GET BACK HERE!
That's the reason behind the buzzer with the lamp :)
Tinkercad had all the components available, open-source, and fairly accurate simulation
This kettle base already had a hole, but tight for the switch. I used a rasp to widen it.

Material used for physical circuit
The dearest Avo for troubleshooting, chasing that lost electron to its inevitable fate...
Circuit schematic on Tinkercad
Current path: follow the red arrows The yellow path only works if S2 is closed
S1: if closed, the lamp turns on
S2: if closed, the buzzer works
Connection between buzzer and lamp: parallel

Final product in action
Developing the logic of the circuit. How to transform the idea of working of each of the switch and button to behave as expected?
For that, I used trial and error. Connect, test, notice, modify.
It would be cleaner, easier, and faster to just think what should be parallel and what series. That would have reduced the number of trials a lot.
Troubleshooting EVERY SINGLE WIRE of this circuit and following the current with the avo was really cool.
My eternal problem with electricity was that I can't grasp that electron thing and need to deal blindly with it. In that session, it was the first time I feel and visualize the current by inspection rather than wishful guessing. Special thanks to Ahmed Sami.
