SHOW DICTIONARIES privilege does not work as expected

[alsugiliazova]

ClickHouse server version 24.4.1

defaults user:

CREATE USER user1;

CREATE DICTIONARY dict
(
    `x` Int32,
    `y` Int32
)
PRIMARY KEY x
SOURCE(CLICKHOUSE())
LIFETIME(MIN 0 MAX 0)
LAYOUT(FLAT());

GRANT SHOW DICTIONARIES ON dict TO user1;
GRANT SELECT ON system.dictionaries TO user1;

SHOW GRANTS FOR user1;

1. GRANT SHOW DICTIONARIES ON default.dict TO user1 
2. GRANT SELECT ON system.dictionaries TO user1     

SELECT name
FROM system.dictionaries

   ┌─name─┐
1. │ dict │
   └──────┘

1 row in set. Elapsed: 0.001 sec. 

SHOW DICTIONARIES

   ┌─name─┐
1. │ dict │
   └──────┘

1 row in set. Elapsed: 0.001 sec. 

user1:

SHOW DICTIONARIES

0 rows in set. Elapsed: 0.001 sec.

SHOW CREATE DICTIONARY dict

CREATE DICTIONARY default.dict
(
    `x` Int32,
    `y` Int32
)
PRIMARY KEY x
SOURCE(CLICKHOUSE())
LIFETIME(MIN 0 MAX 0)
LAYOUT(FLAT()) 

EXISTS dict

Code: 497. DB::Exception: Received from localhost:9000. DB::Exception: user1: Not enough privileges. To execute this query, it's necessary to have the grant SHOW TABLES ON default.dict. (ACCESS_DENIED)

SELECT name
FROM system.dictionaries

0 rows in set. Elapsed: 0.001 sec. 

According to docs, SHOW DICTIONARIES is enough for using EXISTS dictionary.
Why I do not see dictionary when I use SHOW DICTIONARIES?
Why I do not see anything in system.dictionaries?
