Passing generic inside tRPC query

Hi, I hope you're doing well. Server:

findManyUser: publicProcedure.input(UserFindManyArgsSchema).
    query(<I extends Prisma.UserFindManyArgs<DefaultArgs>>({ input }: { input: I }) => {
      return prisma.user.findMany(input)
    })

findManyUser: publicProcedure.input(UserFindManyArgsSchema).
    query(<I extends Prisma.UserFindManyArgs<DefaultArgs>>({ input }: { input: I }) => {
      return prisma.user.findMany(input)
    })

Nextjs front:

const users = trpc.findManyUser.useQuery({include:{image:true}  })
//users : UseTRPCQueryResult<PrismaResultForFindMany<DefaultArgs>, TRPCClientErrorLike<{ input: Prisma.UserFindManyArgs<DefaultArgs>; output: PrismaResultForFindMany<DefaultArgs>; transformer: true;errorShape: DefaultErrorShape;}>>

const users = trpc.findManyUser.useQuery({include:{image:true}  })
//users : UseTRPCQueryResult<PrismaResultForFindMany<DefaultArgs>, TRPCClientErrorLike<{ input: Prisma.UserFindManyArgs<DefaultArgs>; output: PrismaResultForFindMany<DefaultArgs>; transformer: true;errorShape: DefaultErrorShape;}>>

I would like to pass the type of my Prisma query ({ include: { image: true } }) to findManyUser, so users has the expected type and not the default type provided by Prisma (without generics : DefaultArgs ). Thanks for your help. Have a great day/night!

Thank you very much, I am now sure that it's not doable right now 🤍 Have an excellent day! (PS: I will close the post at the end of the day if anyone wants to add something in the meantime)
