LegacyAlertCompanyComparisonExpression
Allows filtering Alerts by the Company they were created for. Works for both "comapny" and "relatedCompanies" field.
When used, "relatedCompanies" will still return a full list of Companies related to the Alert, but at least one of those companies will need to match this expression for the Alert to be returned by the API.
