Laravel multiple database can not connect

[gbekura]

We are encoutering troubles with connecting platform sh Databases to laravel.

for example we have services yml:

# The name of the service container. Must be unique within a project.
db5:
    type: mariadb:11.2
    disk: 2048
    configuration:
        schemas:
            - archfix_ibc
            - archfix_static
        endpoints:
            mysql:
                default_schema: archfix_ibc
                privileges:
                    archfix_ibc: admin
            mysql2:
                default_schema: archfix_static
                privileges:
                    archfix_static: admin

And app relationships:

relationships:
    mysql: 
        service: db5
        endpoint: mysql
    mysql2: 
        service: db5
        endpoint: mysql2

database.php db configs:

        'mysql2' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST_2', '127.0.0.1'),
            'port' => env('DB_PORT_2', '30001'),
            'database' => env('DB_DATABASE_2', 'archfix_static'),
            'username' => env('DB_USERNAME_2', 'user'),
            'password' => env('DB_PASSWORD_2', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ],
        
        'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ],

And it won't connect to the database. User manual lacks information about non standard cases.

I assume that it only works if relationship is called database and laravel app has only one database.
