How to define an async procedure?

export const exampleRouter = createTRPCRouter({
  hello: publicProcedure
    .input(z.object({ text: z.string() }))
    .query(({ input }) => {
      return {
        greeting: `Hello ${input.text}`,
      };
    }),

  getAll: publicProcedure.query(({ ctx }) => {
    return ctx.prisma.example.findMany();
  }),

  getSecretMessage: protectedProcedure.query(() => {
    return "you can now see this secret message!";
  }),
  initAgones: publicProcedure.query(async () => {

    const connectRes = await agonesSDK.connect();
    console.log({connectRes});
    
    return 'test';
  })
});
