Dedicated Pooler only showing 1 connection

We're running a FastAPI app on Cloud Run that scales horizontally, so we want to use the dedicated pooler instead of having to maintain pools in app, per container with AsyncPg. We have the pro plan and a micro instance on Dev. I changed my env to 6543 on local to check if it works as expected, but my DB connections count increases, but dedicated pooler client connections has been 1 forever. I even made 1000 requests to my App in over 2mins, with several DB operations, but it stayed 1. Am I doing something wrong?
