Options
client: QueryClient

Required
the QueryClient instance to provide
contextSharing: boolean

Deprecated
defaults to false
Set this to true to enable context sharing, which will share the first and at least one instance of the context across the window to ensure that if React Query is used across different bundles or microfrontends they will all use the same instance of context, regardless of module scoping.
