how to take line breaking?

[Sunia2021]

at first, thanks for sharing such a powerful plugin!!
In my project, need to render Latex, and so choose this plugin!
i am a tyro, now i can render Latex string, but have a big question -- how to take line breaking?
two cases：
1.latex string is wider then screen width 2.one latex string has multi-math expression
In Math.tex( ).texBreak().parts, how can we make custom line breaking policy? i did not get the key!
thanks for any help~~
