A question about user atributes

I am trting to do something, and it ias not working as I think it should.

Consider:

onnected to a database called stan as stan

/dt reports

List of relations
Schema |           Name           | Type  | Owner 
 --------+--------------------------+-------+-------
 ica    | biz_constants            | table | stan
 ica    | bom_item                 | table | stan
 ica    | costing_unit             | table | stan
 ica    | customer                 | table | stan
 ica    | employee                 | table | stan

 Connect as user postgres to database stan and execute:

 grant all ON ALL TABLES IN SCHEMA ica to harec ;

 Connect to database stan as user harec

 stan=> \dt
 Did not find any relations.
 stan=> \c
 psql (12.1 (Debian 12.1-1.pgdg100+1), server 11.6 (Debian
 11.6-1.pgdg100+1))
 You are now connected to database "stan" as user "harec".
 stan=> 

 What am I doing wrong?
