Does chewing hard gum like Falim cause TMJ or other jaw problems?

I’ve been looking into looksmaxxing and a lot of people have recommended to chew hard gums like Falim gum or mastic gum in order to train the masseter muscle which can contribute to a wide jaw, but anyways as I looked into this I noticed a few videos saying that accessing chewing can cause TMJ issues.

Can I please get some clarity on this issue as well as safe methods to chew gum. Thankss 😊
