Is there a way to set a types for queryClient without casting everytime?

Hello, I have a custom useQuery hook: 
export function useGetChannels(userId: string | undefined) {
  return useQuery({
    queryKey: ["channels"],
    queryFn: () => fetchChannels({ userId, pageParam: 0 }),
    enabled: !!userId,
  });
}
export function useGetChannels(userId: string | undefined) {
  return useQuery({
    queryKey: ["channels"],
    queryFn: () => fetchChannels({ userId, pageParam: 0 }),
    enabled: !!userId,
  });
}
I want to access this query using queryClient, but the type is unknown: 
  const channelsQueryData = queryClient.getQueryData(["channels"]);
  const channelsQueryData = queryClient.getQueryData(["channels"]);
is there a way for me to set the types for channels, so that I will be able to access it without having to cast it evertytime i use the getQueryData or setQueryData?

nope, you need querClient.getQueryData<Channels>["channels"] but out of curiosity: why do you need getQueryData , apart from optimstic updates ?
