Accessing Salesforce eventlog files can't be done from the setup menu of your Salesforce org. The only way is to leverage the API to get it.
This tool will show you the list of Eventlog files that are available for download. Just one click later you will start downloading the file.
This tool is secure, log files are directly transfered from the Salesforce server to your browser. No server processing. For this reason you need to add https://jla.ovh to the CORS setting of your org.
