How do I add headings in an include to a page TOC?

[Laura Novich]

I have a Confluence page which has an /include. In the included snippet, there are several headings. None of these headings appear on the page TOC.
How do I remedy this?

Hi @Laura Novich 

Unfortunately it will not work :( not like on DC

Here the documentation : https://support.atlassian.com/confluence-cloud/docs/insert-the-table-of-contents-macro/

it says, "The macro only works within the page, blog, or macro to which it has been added, and cannot reference or be referenced across multiple pages or blogs. 

Regards,
