Accessing the semantic index

Question

Hi,

Can the semantic index created for Copilot be accessed/searched? If I understand correctly this is created automatically for each Copilot user and is controlled by Microsoft Graph. I'd like to build an application that uses semantic search on user's Sharepoint to retrieve relevant information (and then processes this data further). I'd prefer to use the semantic index created for Copilot instead of duplicating efforts and creating another index e.g. using Azure AI Search. Could you tell me if this possible, please?

Thanks
