Requires latex functionality

I really need latex \limits_, \argmin, etc. I hope it can be added, thanks!

Can you give an example what it should look like?

Maybe this is usefull, you can add custom commands by using:

$$
\newcommand{\argmin}{...}
$$

How do I achieve this effect?
image
image

$$
\DeclareMathOperator*{\argmin}{arg\,min}
\DeclareMathOperator*{\argmax}{arg\,max}
$$

$$
\argmin_{text}
$$

$$
\argmax_{text}
$$

For limits you can just do this:

$$
\lim_{x\to\infty} f(x)
$$

Thank you so much!
