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?
