If you don't want to play around with 220V (I don't want), then the alternative way is to use a low energy single board like an ESP8266, build a web server on it and let the esp shut down the pi with a remote switch (connected to the Shutdown pin of the GPIO of the raspi) and after some delay cut off the 5V power connection to the pi. You can use something like this here: https://www.aliexpress.com/item/32615078664.html . All you need is to route the 5V through it, and all you need is two of those here: https://www.aliexpress.com/item/1005002320414960.html so you can connect a power cable on both ends
