How do I adjust all my lines to be the same lineweight?

I saw this function from Clip Studio about making all the lines in it uniform in weight: https://tips.clip-studio.com/en-us/articles/2767
and I was wondering if Krita 5 had a function like this too.

Does Krita have its own way of “slimming” down lineart like Clip Studio does as well?

Quote from the link you provide:

However, this technique can only be used when the original line art is drawn on a vector layer

I think it is currently not possible to do in CSP way, need some other trick to achieve similar result in krita.
