PostgreSQL version: 13.1

Description:
In the following SQL statement, parallel_leader_participation's category is

name='parallel_leader_participation';
-[ RECORD 1

postgres=#
but in the documents
(https://www.postgresql.org/docs/13/runtime-config-query.html#RUNTIME-CONFIG-QUERY-OTHER)
parallel_leader_participation's category is 'Query Tuning / Other Planner
Options'
and in the category "Asynchronous
Behavior"(https://www.postgresql.org/docs/13/runtime-config-resource.html#RUNTIME-CONFIG-RESOURCE-ASYNC-BEHAVI...
is no parallel_leader_participation parameter.
so, what is parallel_leader_participation's category ?
