Can the customer checkout dashboard help identify bottlenecks?

Good morning, I have been running a Shopify store over the past couple of months now, and I feel that it could be doing better. I'm looking for a way to identify bottlenecks and optimize my store. I've tried customer journey mapping, but the results haven't been conclusive. I then wondered if the problem could be lying in the checkout process of my store. When I tried looking for metrics or a way to analyze it, I found a customer checkout dashboard (which I'm unfamiliar with) that I have to pay for. But I don't want to pay for something and then it's useless in the end. Should I get it?
