Focused View - CORS issue on Mobile Devices

Hi,
We have implemented Embedded Signing - FOCUSED View in our PWA (Progressive Web Application)
In Browser its working fine

In Native app, its throwing cors error, and also I found out from the documentation that Docusign doesn't support localhost in prod.
Host_Origin for
Android: http://localhost
IOS: capacitor://localhost

So, what are the options we have??

Thank you
