How to do a Code Report Coverage in UI Automation Test?

We are a UI Automation Test team and we use CodeceptJS to create acceptance tests in a web application made with Angular 1.x.

We’ve been thinking about doing a Code Report Coverage on the client-side of the web application, but we don’t know too much about it and what we’ve found until now on the internet is not deep enough to help us get started.

Does someone know how to do it? If yes, can someone give us a direction or some reference that can help our team?

Thanks in advance.

Best regards,
