Narrowing Types in a Discriminated Union with Effect.filter

const filteredBlocks = yield* Effect.filter(blocks, (block: typeof confectSchema.tableSchemas.profile_blocks.withSystemFields.Type) => Effect.succeed(
  block.kind === "experience"
))

const filteredBlocks = yield* Effect.filter(blocks, (block: typeof confectSchema.tableSchemas.profile_blocks.withSystemFields.Type) => Effect.succeed(
  block.kind === "experience"
))

I feel like I'm going crazy with this. I've got a discriminated union and I want to extract blocks of a specific

kind

kind

and get a subset of that array. However the types are not being narrowed properly. How can I approach this?
