aws documentation for DMS CDC is confusing

I am following this documentation https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.PostgreSQL.html#CHAP_Source.PostgreSQL.Security to enable CDC using logical replication. I have pglogical extension installed and added under "shared_preload_libraries" parameter. Replication slot created fine - SELECT * FROM pg_create_logical_replication_slot('test_slot', 'pglogical'); but why do i get this error when creating replication set as exactly mentioned in the document? select pglogical.create_replication_set('test_slot', false, true, true, false); ERROR: current database is not configured as pglogical node HINT: create pglogical node first However, Creating pglogical node step is ONLY covered under a different topic of "Using native CDC..." in the same URL - https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.PostgreSQL.html#CHAP_Source.PostgreSQL.v10 Can someone please explain the right steps on how to enable logical replication via AWS DMS CDC? is native cdc different than DMS CDC?
