The syntax for the overlay should be the same, but a lot can change in nearly 4 years (Buster was dropped in Nov 2021 when Bullseye came out).
The kernel should handle the basic mappings, with the default being rc-rc6-mce.
If you "sudo apt install evtest" and run evtest selecting the relevant input device, do you get any input events?
It also uses interrupts on the GPIO pin, so /proc/interrupts should list something like "pinctrl-bcm2835 <GPIO> Edge gpio-ir-recv-irq", and the number in the second column should increase as IR events are detected. If that column doesn't increase, then you're likely looking for a wiring issue.
