How to filter resource using indirect relation?

[whatuserever]

I have a Prisma schema where my admin has a list of containers, and each container has a list of items:

Prisma schema

model Admin {
  id         Int         @id @default(autoincrement())
  containers Container[]
}

model Container {
  id      Int    @id @default(autoincrement())
  Admin   Admin  @relation(fields: [adminId], references: [id])
  adminId Int
  items   Item[]
}

model Item {
  id          Int       @id @default(autoincrement())
  Container   Container @relation(fields: [containerId], references: [id])
  containerId Int
}

How can I make sure the resource page for Item only shows items belonging to the current admin?

I tried adding a filter using the before hook, but was unsuccessful:

function filterByAdminId(request: ActionRequest, context: ActionContext): ActionRequest {
  request.query['filters.container.admin'] = context.currentAdmin.id;
  return request;
}

This shows an error in the app:

There was an error fetching records. Check out console to see more information
