Creating in-article index that references heading types

I am wondering if it is possible to add an index that references specific heading types on a LinkedIn article.

Let's say that I have an article with the following structure:

A bit about me (Heading 1)

About (Heading 2)

Projects (Heading 2)

Services (Heading 2)

And I want to create an in-article index, that allows me to reference headings 1 and 2, and, by pressing, for example, 1. About, it would take me to that specific part of the article.
