I took a few photographs two days ago. I used a mirror-less camera mounted on a tripod in my balcony. Manual settings, ISO 200, f/8 or f/11 and long exposure (from 1 second to 4 seconds). Two seconds worked best around midnight, four seconds allowed more “hits” earlier in the night. I controlled the camera from the sitting room with a tablet connected through Wifi (stepping on the boards in the balcony would have shaken the camera, and it was rather cold!). It is just a question of luck, you have to trigger the shutter before the fireworks are visible and hope for the best.
