How to generate a TOC as a page in the eBook?

Hello,

I wish to create a table of content from headers h1 to h4 so that the headers cascade in an automatically generated html page.

I know that there is the "Modify TOC" button, but I haven't found a way to actually generate a page and further more I wish to put this page in my ebook between two chapters.


The resulting page might look as such

Title1
___Title11
___Title12
Title2
___Title21
______Title 212

Thanks
