CodeWhisperer logs out after some time from VS Code

Hi,

I am using CodeWhisperer with VS Code. When it was a preview, I was using AWS Builder ID to log in and then CodeWhisperer works well in VS Code. I should have repeated this procedure (log in via AWS Builder ID, expiration of AWS Builder ID token) from time to time. But now the service is not in preview and I still need to log in after some time via AWS Builder ID? Is it normal behavior?

Thanks, M
