I am trying to pass the correct format for GraphQL. I can get this to work through post man no issues

 {
   tblprojects
    {
      id
      name
   }
}

I am lost on how to apply operators, filters, etc. When I try this it gives an error

{
   tblprojects (name:"Test")
    {
      id
      name
   }
}

“message”: “Unknown argument “name” on field “tblprojects” of type “Query”.”,

This is the backend

$queryFields = [];
        foreach ($tables as $table) {
            $queryFields[$table] = [
                'type' => Type::listOf(new ObjectType([
                    'name' => ucfirst($table),
                    'fields' => function() use ($table) {
                        return $this->getFieldsFromTable($table);
                    },
                ])),
                'args' => [
                    'id_in' => [
                        'type' => Type::listOf(Type::int()), // Allow filtering by an array of integers
                    ],
                ],
                'resolve' => function($root, $args) use ($table) {
                    if (isset($args['id_in']) && !empty($args['id_in'])) {
                        // Apply filtering if 'id_in' argument is passed
                        $this->db->where_in('id', $args['id_in']);
                    }
                    return $this->db->get($table)->result();
                },
            ];
        }

Looks like I need to pass // Apply filtering if ‘id_in’ argument is passed
How do I do this? Can you give me a few examples of applying operators and filtering etc so I can try in postman?
