UserSelect across functions

Does anyone know how I can type this function such that the caller can optionally provide a

selection

selection

which is then set on the

findUnique

findUnique

and then the return type matches what was selected. If the argument is not set it should return all the fields.

export async function getUser<T extends Omit<UserFindUniqueArgs, "where">>(
  userId: number,
  options: T,
): Promise</** WHAT TO PUT HERE? */> {
  const user = await database.user.findUnique({
    where: { id: userId },
    ...options,
  });

  if (!user) {
    throw data(
      { error: `User with ID "${userId}" does not exist` },
      { status: 400 },
    );
  }

  return user;
}

export async function getUser<T extends Omit<UserFindUniqueArgs, "where">>(
  userId: number,
  options: T,
): Promise</** WHAT TO PUT HERE? */> {
  const user = await database.user.findUnique({
    where: { id: userId },
    ...options,
  });

  if (!user) {
    throw data(
      { error: `User with ID "${userId}" does not exist` },
      { status: 400 },
    );
  }

  return user;
}

I don't know how useful this utility function is but it saves me from typng all this
every time. Downside is that I'd also need to implement

omit

omit

here and supposedly

include

include

according to the docs but in my IDE it says that field does not exist for findUnique
