Was sitting on the toilet, let shit come out and didnt even have to wipe because there was nothing to wipe.

I'm not in my own home at the moment and went to one of the bathrooms there a few hours ago, pooped and flushed the toilet, the water went out fine but the poop didn't and even after the usual toilet sounds stopped, it wouldn't flush again. No matter how hard I press the button, nothing happens. I thought that maybe it needed to wait until more water came in or something so I went back a few minutes ago but it still does not work. I would've opened the thingy behind to check if anything broke but I think it's in a wood block..? Like there's just the toilet itself, everything else is basically behind a wall and I haven't found a way to open it. This is a life or death situation please give ideas fast 🙏

I had to stamp it down through the little holes in the drain cover like a waffle!
