Help with Prisma Validator static evaluation

I am trying to build a helper function that will allow me to abstract away some deeply nested includes for a data type. However I'm trying to make this reusable like in the following snippet

export const helper = (include: boolean) => {
  return Prisma.validator<Prisma.SomeInclude>()({
    include: {
      someTable: include
    }
  })

export const helper = (include: boolean) => {
  return Prisma.validator<Prisma.SomeInclude>()({
    include: {
      someTable: include
    }
  })

The issue with this is that I wish it would correctly map when passing true to { include: { someTable: true } }. Any wizards that could help?

I am not sure I follow, could you elaborate?

Sure. The issue I'm having is that if I use the helper as shown above in a query I get partial types, because it maps to

{ include: {someTable: boolean}}

{ include: {someTable: boolean}}

I'd like it to, for example:

const values = await prisma.table,findMany({
  include: helper(true)
})

const values = await prisma.table,findMany({
  include: helper(true)
})

and have the result be Table & {someTable: ItsType} when I pass true, it currently returns Table & {someTable?: ItsType}
