Fast TOC is a WordPress plugin that generates a table of contents from the headers in your post.
Installing and basic working
After you selected the post types you want to have a table of contents in the settings, you can (de)select it for each separate post in the Gutenberg document sidebar.
A TOC is generated by scanning all the header elements (H1 until H6) in the post. By default it is placed on top of the page, but you can specify a different position by using the fast-toc shortcode.
Go the the Settings / Reading section after installing the plugin. There you can setup the plugin. Below all settings are explained.

Example non-nested numbers

Nested number separator
