Internal Link in a Exported HTML

[OsicKwon]

Hi,

I tried to make an internal link worked in an exported html, which didn't work for me.
Is it possible to do that?

---
title: test internal link

markmap:
    activeNode:
        placement: center
---



# main



## sub-main1
- Go to [sub-main2](#sub-main2)


## sub-main2
- Go to [sub-main1](#sub-main1)

Exported HTML is at the bottom right of the screen below.
