This is the “docs” page referenced from the ir module product page
https://docs.m5stack.com/en/unit/ir
it mentions GPIO36 - Receiver pin. I’ve also seen a few blogs that indicate GPIO 36… one guy actually talked about GPIO32 in the text of his blog, but in the code he had GPIO36…
however I have tried GPIO 32 - it’s been a few days, will just try again.
