How can I create a function that takes in a Prisma object and let the return type be based on the included relations?

My goal is that versionWithRelations is typed as having the properties pages, variables, and actions, while versionWithoutRelations does not.

Here is my current attempt:

import { Prisma } from "@prisma/client";

const getVersion = <
  Relations extends Prisma.AppVersionInclude,
  App extends Prisma.AppGetPayload<{
    include: { versions: { include: Relations } };
  }>,
>(
  app: App,
): Prisma.AppVersionGetPayload<{ include: Relations }> => {
  return app.versions[0]!;
};

const withRelations = await prisma.app.findUnique({
  where: { id: "foo" },
  include: {
    versions: {
      include: {
        pages: true,
        variables: true,
        actions: true,
      },
    },
  },
});

const withoutRelations = await prisma.app.findUnique({
  where: { id: "foo" },
  include: {
    versions: true,
  },
});
const versionWithRelations = getVersion(withRelations!);
const versionWithoutRelations = getVersion(withoutRelations!);
