Katex - how to jump to the equation

Question

I want to use katex (https://katex.org/docs/support_table) to generate math symbols on my website. The environments like align generates numbers like below

I'd like to add a button which scroll to lets say equation 3. What would be the better way to do that? Katex doesnt generate id for equation numbers. Should I postprocess the output of katex and add it?
