Attaching to multiple localhost workers via vscode? What's the port I need to give?

Hi, the advice in the following link doesn't seem to work if I try to attach to multiple running workers on localhost and attaching to them: https://developers.cloudflare.com/workers/observability/dev-tools/breakpoints/ The link mentions port 9229, it makes sense that I'd need to give a different one for each debugger but where would I see which port gets used and how do I configure that? Thank you
