Accessing the Schema of a Struct Property in TypeScript

// In another project, only access to CanvasQuoteSettings
export class CanvasQuoteSettings extends Schema.Class<CanvasQuoteSettings>(
  "CanvasQuoteSettings",
)({
  instructions: Schema.Array(DrawInstruction),
}) {}

// Separate project:
export const CanvasWorkerMarco = Schema.TaggedStruct("ceapp/CanvasWorkerMarco", {
    instructions: CanvasQuoteSettings['instructions'], // <--- how to do this?
    canvas: Schema.instanceOf(OffscreenCanvas),
})
