Cannot Setup Microsoft Azure AI Video Indexer ARM Account on Microsoft Azure AI Video Indexer Web Portal

I’ve set up a new resource group for Microsoft Azure AI Video Indexer with the service and StorageV2 successfully. I used the same account for both Azure and Azure AI Video Indexer. However, when I open the Video Indexer Web Portal, I still see a TRIAL badge.

When I click Create Unlimited Account under the profile section, it navigates me to creating a new resource in the Azure Portal.

How can I merge my existing Microsoft Azure AI Video Indexer resource group with the Microsoft Azure AI Video Indexer Web Portal?

Thanks.
