Need help recovering account owner.

Problem: Account owner cannot sign in with its password after SSO was configured. Account owner is a DL for team ownership so it doesn't have an AWS account and can't configure in AD group since it has "+" in the email.

History:

• Account owner created databricks account
• Account owner created workspace
• Account owner added groups and users of team that has AWS accounts
• All accounts are able to sign in with SSO to workspace besides the account owner
• Account owner now can't log in to https://accounts.cloud.databricks.com/ since sso is required, but there is no aws account for this user.
