This isn't a direct answer to your question, but be very careful with asking for HAR files. They're super convenient, but if your tech support doesn't understand that HAR files are the worst kind of PII you can get in big trouble.

I've seen HAR files containing Google account session tokens attached in plain text to Jira tickets. If you end up leaking those tokens your customers will not be amused.
