Scenario

The Support team has advised you to provide a HAR file for the issue occurring for further analysis.

Additional info: HAR files contain sensitive data, including the page content you downloaded while recording and your cookies. This can allow anyone with the HAR file to impersonate your account and all the information that you submitted while recording (this can include personal details, passwords, credit card numbers, and so on).
