Question: Is there a way to have a base interface for Trpc router?

interface A { function X(L: string){} }

class B implements A {} // error missing function X

interface MyMethods {
  stateSubscribe: (
    input: undefined,
    opts: { onData: (state: string) => void },
  ) => void;
}

export const campaignRouter = createTRPCRouter<MyMethods>({
  createCampaign: protectedProcedure.query(({ ctx }) => {
    throw new TRPCError({
      message: "Not implemented",
      code: "NOT_IMPLEMENTED",
    });
  }),
  stateSubscribe: protectedProcedure.query(({ ctx }) => {
    throw new TRPCError({
      message: "Not implemented",
      code: "NOT_IMPLEMENTED",
    });
  }),
});
