Why is Vivox Credentials(API key) on UGS different from the vivox developer portal

The latest version Vivox Unity SDK can only use Credentials(API keys) for UGS, but cannot use another Credentials(API keys) for vivox developer portal.

Is the application on the vivox developer portal no longer supported?

or,
How to use credentials (API key) for vivox developer portal on Unity?

Hello! To help me best answer your question, can you confirm whether you’re using the Unity Vivox SDK through the Unity Engine Package Manager, or the download from the Developer Portal’s downloads page? Thanks for your cooperation!
