Testing with weblink or other way to use run mode

Hello, I'm recently trying to share our beta service before publishing on store.

The only way that I can share my code is

  1. Sharing run mode link to my FF team member

  2. Sharing web deployed link

Option 2 is perfect for testing, cause everyone can access with their phone, laptop... But, it has API Cors problem with web deployment.

Is there any way to fix this cors problem or share run mode flexibly with others?
