I am attempting to get a TOC that looks like the following (in other words with section titles and their relative page numbers in a block below the chapter):

Chapter 1 ...................................................5

Section 1   5, Section 2  6, Section 3  7,

Section 4   8, Section 5   9 etc  

Chapter 2 ................................................10

Section 1   10, Section 2  11, Section 3  12,

Section 4   13, Section 5   14 etc 

As I really had no idea how to do this, I found https://wiki.contextgarden.net/Horizontal_Table_of_Contents thinking it might help, but none of it compiles (for me) in LMTX. So I tried something different, e.g.

[...]

While that produces a result, it is nothing like what I want above. Has anyone put together a TOC of this kind and might be able to give me a hint to follow?
