Impossible to use "itemOperation" and "collectionOperation" attribute with api-platform/core 3.0

[ghost]

How can we use "collectionOperation" or "itemOperation" with api-platform since 2.7 ?

use ApiPlatform\Metadata\ApiResource;

### 

#[ApiResource(
    collectionOperations: [],
    itemOperations: [],
)]

doesn't work anymore ...
