Postgresql 2 users with different permissions on a specific schema - sql

Question

i have a postgresql 11 database with the public schema. I have a role user1 that has all privileges on schema public.
i would like to do the following :
create a schema "some_schema";
grant read only privileges to user1 to "some_schema";
create role user2 that has all privilegies on schema "some_schema".
I tried the following :
CREATE USER user2 WITH PASSWORD '***';
CREATE schema "some_schema";
GRANT CONNECT ON DATABASE user1 TO some_schema;
GRANT USAGE ON SCHEMA some_schema TO user1;
GRANT ALL ON SCHEMA some_schema to user2;
ALTER DEFAULT PRIVILEGES IN SCHEMA some_schema GRANT SELECT ON TABLES TO user1;
This does not work cause when i login like this and then i create a "test" table and select, it puts that user1 that "relation 'some_schema.test' doesn't exist" :
create table some_shema.test(id int);
\q
psql -U user1;
select * from some_schema.test;
result => relation some_schema.test doesn't exist.
I also changed the pg_hba.conf to give access to the new schema to both users and restarted the server.
I've tried to read the documentation and many things without success. Maybe it's the way i connect to the database ?
thank you.

Thank you #JGH, that was it. : the user2 had to give himself access to user1 to schema some_shema.
What i did :
psql
CREATE USER user2 WITH PASSWORD '***';
\c my_database
CREATE SCHEMA some_schema AUTHORIZATION user2;
\c my_database user2
create table some_schema.test(id int);
insert into some_schema.t(100);
GRANT USAGE ON SCHEMA some_schema TO user1;
GRANT SELECT ON ALL TABLES IN SCHEMA some_schema TO user1;
ALTER DEFAULT PRIVILEGES IN SCHEMA some_schema GRANT SELECT ON TABLES TO user1;
then :
\c my_database user1
select * from some_schema.t;
=> shows result 100 :)
