Verify if user has replication permissions in Postgres

Question

I am working on streaming changes in my Postgres database using Debezium using the Postgres connector offered by Postgres. However, for the connector to work, the user must have REPLICATION and LOGIN rights. Although, the problem seems to be as simple as checking permissions in pg_roles, it is not.

For example, I have a user with following permissions :

  rolname   | rolsuper | rolinherit | rolcreaterole | rolcreatedb | rolcanlogin | rolreplication | rolconnlimit | rolpassword | rolvaliduntil | rolbypassrls | rolconfig |  oid
------------+----------+------------+---------------+-------------+-------------+----------------+--------------+-------------+---------------+--------------+-----------+-------
 test_user  | f        | t          | f             | f           | t           | f              |           -1 | ********    |               | f            |           | 36123

The test_user has rolreplication as false even then I am able to create a replication slot using the user. Can anyone show some light about what exactly is the right method to get all privileges available to the user?

I also tried looking into the groups of which test_user is a member but those groups also do not have the rolreplication as true. Here we are talking about logical_replication and not physical_replication. Am I missing something or is there any other table or query which I should use to get this?

EDIT :

Running select * from pg_replication_slots gives:

slot_name  |  plugin  | slot_type | datoid |   database    | temporary | active | active_pid | xmin | catalog_xmin | restart_lsn  | confirmed_flush_lsn
-----------------------------------------------------------+----------+-----------+--------+---------------+-----------+--------+------------+------+--------------+--------------+---------------------
test_slot  | wal2json | logical   |  60811 | test_database | f         | t      |      21642 |      |      5955602 | 1FD/D00BA2E0 | 1FD/D107C598
