Logical replication with VPS postgresql server as publisher and aiven postgresql database as subscriber

Hello everyone,
I need some assistance, I have set up the logical replication on my postgresql database and using aiven_extras, set up subscription on my aiven postgresql database.
However my problems are:

  1. After following all the steps in this guide ’ Set up logical replication to Aiven for PostgreSQL’ (I cannot embed the active link) then running this query SELECT slot_name,restart_lsn FROM pg_replication_slots; the data, the slot I create doesn’t reflect in the returned table, only “pghoard_local” shows.
  2. The data does not replicate.
  3. I do not get any errors in my publisher.

Questions
How can I go about this please, I need help
