import { createStep } from "@mediar-ai/workflow";

export const fillForm = createStep({
  id: "fill_form",
  execute: async ({ desktop, logger }) => {
    // Find and click submit button
    const btn = await desktop
      .locator("role:Button")
      .first(2000);
    await btn.click();

    // Type in email field
    const input = await desktop
      .locator("role:Edit")
      .first(2000);
    input.typeText("user@example.com");
  },
});
