With recusive miss syntax definition

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/15/queries-with.html
Description:

In this page seems to miss link to with sintax.
Specially for with recursive.
I'm looking for an more complicated example like that:
with first_query as (
), recusive_second_query as (
select fields from first_query
union all
select fields from second_query
join other query
)

But it seems "recusive" could be used just for first query.

But this information should be explained
