Answer 1

The CDK must have changed this was created. I got it working with the example from @CCarlos:

const pool = new cognito.CfnUserPool(this, "cdkUserpool", {
  userPoolName: "cdkUserPoolName",
  usernameAttributes: ["email"],
});
const client = new cognito.CfnUserPoolClient(this, "cdkClient", {
  userPoolId: pool.ref, // <--- This part has changed.
  explicitAuthFlows: ["ADMIN_NO_SRP_AUTH"],
  generateSecret: false,
  readAttributes: [
    "preferred_username",
    "website",
    "email",
    "name",
    "zoneinfo",
    "phone_number",
    "phone_number_verified",
    "email_verified",
  ],
  writeAttributes: ["name", "zoneinfo", "phone_number"],
});
