Would like this extension to work with the sidebar of a book project

[ercbk]

Saw in quarto issue "How to use custom icons?" (#5816) that this extension worked with the navbar of websites. I tried to get this work with the website sidebar of a book project, but I couldn't get the icon to appear.

book:
  sidebar: 
     tools: 
        - text: "{{< iconify fa6-regular heart >}}"
          href: https://ercbk.github.io/Statistical-Rethinking-Notebook/

I tried using "icon" instead of "text," but that doesn't work either. I also inserted the shortcode in one of HTML documents in the project, and it worked there. So, I figure the extension is installed correctly.
Anyways, I was wondering if it was possible to make this extension work with the website sidebar of quarto book projects. Thank you.

The issue is from Quarto, not the extension, as in this context "text" is used as title and aria-label.

<div class="sidebar-tools-main">
  <a href="https://ercbk.github.io/Statistical-Rethinking-Notebook/" rel="" title="{{< iconify fa6-regular heart >}}"
    class="quarto-navigation-tool px-1" aria-label="{{< iconify fa6-regular heart >}}">
    <i class="bi bi-"></i>
  </a>
</div>

Thanks I'll bring it up with them.

To note, it might be intended to work this way. I started an informal discussion about this, but feel free to formally open an issue to ask about this.

See https://quarto.org/docs/reference/projects/books.html#sidebar-tools for the current (incomplete) documentation. I will also open some issues about the documentation itself.
