Permission denied for schema public at character x

I am using postgresql 15 and I tried running these:

grant all privileges on database my_database to my_database_user;
grant all privileges on all tables in schema public to my_database_user;
grant all privileges on all sequences in schema public to my_database_user;
grant all privileges on all functions in schema public to my_database_user;

but when I run:

php artisan migrate --seed 

I got:

SQLSTATE[42501]: Insufficient privilege: 7 ERROR: permission denied for schema public at character 14 (SQL: create table "migrations" ("id" serial primary key not null, "migration" varchar(255) not null, "batch" integer not null))

What I am missing?

I do make sure .env has correct credentials:

DB_CONNECTION=pgsql
DB_HOST=127.0.0.1
DB_PORT=5432
DB_DATABASE=my_database
DB_USERNAME=my_database_user
DB_PASSWORD=password

Checking that I did:

postgres=# \du my_database_user
            List of roles
  Role name  | Attributes | Member of 
-------------+------------+-----------
 my_database_user |            | {}

and:

postgres=# SELECT * FROM pg_roles;
          rolname          | rolsuper | rolinherit | rolcreaterole | rolcreatedb | rolcanlogin | rolreplication | rolconnlimit | rolpassword | rolvaliduntil | rolbypassrls | rolconfig |  oid
