Allows you to define custom alerts that can be displayed in the dashboard.

```ts title="Signature"
interface DashboardAlertDefinition<TResponse = any> {
    id: string;
    title: string | ((data: TResponse) => string);
    description?: string | ((data: TResponse) => string);
    severity: AlertSeverity | ((data: TResponse) => AlertSeverity);
    check: () => Promise<TResponse> | TResponse;
    shouldShow: (data: TResponse) => boolean;
    recheckInterval?: number;
    actions?: Array<{
        label: string;
        onClick: (args: { data: TResponse; dismiss: () => void }) => void | Promise<any>;
    }>;
}
```

<div className="members-wrapper">

A unique identifier for the alert.
### title

### severity

<MemberInfo kind="property" type={``AlertSeverity | ((data: TResponse) => AlertSeverity)``}   />

The severity level of the alert.
### check

<MemberInfo kind="property" type={``() => Promise<TResponse> | TResponse``}   />

A function that checks the condition and returns the response data.
### shouldShow

<MemberInfo kind="property" type={``(data: TResponse) => boolean``}   />

A function that determines whether the alert should be rendered based on the response data.
### recheckInterval

<MemberInfo kind="property" type={`number`}   />

The interval in milliseconds to recheck the condition.
### actions

<MemberInfo kind="property" type={``Array<{         label: string;         onClick: (args: { data: TResponse; dismiss: () => void }) => void | Promise<any>;     }>``}   />

Optional actions that can be performed when the alert is shown.

The `onClick()` handler will receive the data returned by the `check` function,
as well as a `dismiss()` function that can be used to immediately dismiss the
current alert.
