MessageBox / Input Dialog in Uipath attended cross-platform workflow

Hi @CookieMonster

Please check the below link.

Or you can try below.

Use Form Designer (Modern) for interactive prompts. Use Log Message/Write Line for notifications. Use Write Text File + Read Text File for saving and retrieving decisions.
Use Send SMTP/Outlook Mail Message for email-based confirmation. Use Delay to pause execution.

If you found helpful mark as a solution.
