I have just started out and wanted to confirm if Claude Pro is needed as a minimum to start out? At this day 1 task - step..."2. Connect your Anthropic account Run claude in your terminal. It opens a browser window and asks you to authorise. If you don't have an Anthropic account, create one" it' not opening the browser, it provides a link and then asks for me to sign up to "pro" or "max". Just looking to see if I need Pro or if I have done something wrong.

I have a career in Procurement and am looking to understand more about how AI Agents work and how I can use AI Agents both at work and at home to improve my productivity and also help make better investment decisions.
