How do I get NEL reports

I’m not sure if this is the correct category, but I’m trying to figure out how I get the NEL reports.
I have Network Error Logging enabled and our endpoint is pointing to https://a.nel.cloudflare.com/report/v3](https://a.nel.cloudflare.com/report/v3.
Please note I have not included the full endpoint URL.
The group is cf-nel (“group”:“cf-nel”,“max_age”:604800).
I’m assuming the endpoint was automatically added by Cloudflare, since we did not configure this.
I was actually able to get this information using a tool that scans headers:
https://securityheaders.com](https://securityheaders.com
Our CSP policy has report-to set to cf-nel.
We are using the Free plan.
