useMutation | Typescript generics improvements

[woozie]

Describe the bug
Please correct me if i'm using useMutation incorrectly but there are no good examples in the documentation

To Reproduce
Just write any mutation with generics

const {
  onDone: onSettingsUpdated,
  onError: onSettingsUpdateFailed,
  mutate: submitSettings,
} = useMutation<{
  settings: IProjects.ProjectSettings
}>(UpdateProjectSettingsMutation, { fetchPolicy: 'no-cache' })

onSettingsUpdated(({ data: { settings } }) => {
  toast.success(t('settings.notifications.settingsSaved'))
})

and in line

onSettingsUpdated(({ data: { settings } }) => {

compilation failed

src/components/views/ProjectSettingsView.vue:54:30 - error TS2339: Property 'settings' does not exist on type '{ settings: ProjectSettings; } | null | undefined'.

Expected behavior
No compilation errors
