After onTokenRefresh is deprecated, is there any option to handle new token refresh without too much frequency like the old one.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Token refresh was never actually implemented in the JS SDK. The API is a no-op, and we don't plan to implement it anytime soon, so we decided to deprecate and eventually remove it.
@zwu52 Anything to add?

That is correct. The FM registration token is stable in the case where no rotation will be triggered from the backend side. Feel free to follow up while we keep this thread open for a bit longer.
