Feature flags are used to hide experimental features. For Twenty, they are set on workspace level and not on a user level.

## Adding a new feature flag

In `FeatureFlagKey.ts` add the feature flag:

```ts
type FeatureFlagKey =
  | 'IS_FEATURENAME_ENABLED'
  | ...;
```

També afegiu-lo a l'enum en `feature-flag.entity.ts`:

```ts
enum FeatureFlagKeys {
    IsFeatureNameEnabled = 'IS_FEATURENAME_ENABLED',
    ...
}
```

To apply a feature flag on a **backend** feature use:

```ts
@Gate({
  featureFlag: 'IS_FEATURENAME_ENABLED',
})
```

To apply a feature flag on a **frontend** feature use:

```ts
const isFeatureNameEnabled = useIsFeatureEnabled('IS_FEATURENAME_ENABLED');
```
