How to mimic hard chewing

[Michelangelo]

how to mimic chewing and train the same muscles that are used to actually chew hard and chewy food? i see stuff like chewy gums and silicon pieces for training the jawline, but i was wondering if there was something else that someone could do to stimulate the same muscles. i guess mewing kinda helps, what else? ofc diet is also another thing but im talking about excercises etc that someone could do when not eating or whatever
