How to create TOC Component in Next.js

[kimizuy]

I've created a blog with a new tutorial (It's great tutorial).
And, I wanted to display TOC in my post.

I already know how to use remark-toc and remark-slug.
↓ Here's an image of what it looks like when I use them

This isn't so bad. but I want to see it in the sidebar.
Can I do it with remarkjs?
Do you have any ideas?
