Steps to reproduce:'

• Open Slack in Firefox, notice the Slack instance is switched to the new design (which I cannot revert for my own unprivileged user

• Save HAR for client.userBoot since the new Slack version does not use client.boot anymore

• Re-authenticate -> Import from Browser -> Drop HAR file here

Expected result: Slack finds credentials

Actual result: "Couldn't find Slack account credentials data in this HAR file."

Probably this is expected, assuming client.userBoot uses a different format than client.boot. But because this is an SSO-only Slack instance, which Ripcord cannot sign into directly except using browser credentials, this means I cannot use Ripcord for Slack anymore for now, unfortunately.
