Unable to set landing page

Operating System: Windows

DocFX Version Used: 2.59.4

Template used: ?

    "template": [
      "default",
      "_templates/last-modified"
    ],

Steps to Reproduce:

1. Use the following root toc (resource: DocFX page) to set a markdown doc in a nested folder as the home page for localhost:8080. My understanding is that the root toc.yml generates the top nav bar, and nested toc.ymls generate the vertical left bar. Combining them doesn't seem like a good idea.

- name: Troubleshooting Guides
  href: tsgs/toc.yml
  topicHref: tsgs/aadlcm-oncall-handbook/lcm-dependency-map.md

2. Here's the nested /tsgs/toc.yml:

- name: AADLCM OnCall handbook
  items:
  - name: AAD LCW OnCall HandBook
    href: aadlcm-oncall-handbook/aad-lcw-oncall-handbook.md
  - name: LCM Dependency Map
    href: aadlcm-oncall-handbook/lcm-dependency-map.md

3. Run DocFX locally on the docfx.json in the root folder.

Expected Behavior:

Should see the Markdown article specified by the topicHref as the landing page.

Actual Behavior:

I get an index listing:

Unable to set landing page

Your index page will normally be at the root, what is the folder structure of your output?
An example of my docs generated by DocFX with index.html as the landing page.

Here's the _site folder content:

The index.html is that index page instead of the topicHref doc.

I may be wrong, but my understanding, topicHref does not define the landing page.

By the docs
If homepage topicHref is set for this TOC Item, it will be considered as the href of the expanded TOC Item.

Others were related to links to a folder:

Link to a folder

If the Toc Item is linking to a folder, ending with / explicitly, the link value for the Toc Item is determined in the following steps:

1. If homepage topicHref or homepageUid topicUid is set, the link value is resolved to the relative path to homepage topicHref
2. If homepage topicHref or homepageUid topicUid is not set, DocFX searches for Toc File under the folder, and get the first relative link to local file as the link value for current Toc Item. For example, if the Toc Item is href: article/, and the content of article/toc.yml is as follows:

Thanks Paul, but what I want is to have localhost:8080 show me the left side nav bar and in the home page in the content area. I can rewrite the tocs as needed, I just need someone experienced with DocFx to set me on the right track. Showing the home page would seem like a common scenario.

I also tested the following root toc, but that also failed to show the specified landing page.
