How can I show modal(or popup) when error occurred?

[hwangyena]

I want to display an error popup while keeping the page intact when an error occurs.
As far as I know, react-router provides only the errorElement component, which replaces the existing component with a new one.

How can I achieve this?

I misunderstood React error boundaries, I will close this question.

I also want to implement this kind of feature. Do you know how to do it?
