Expected Outcome:

• USE_PREVIEW_URL accepts URLs without issues.
• Successful testing and verification of the new functionality.

Testing Criteria:

1. Test with various URL inputs to ensure correct functionality.
2. Validate that the changes do not affect other functionalities or environment variables.
