Adv ediscovery export + Custom managed Azure storage with firewall restrictions

Hi all - we are using customer managed Azure storage for Adv ediscovery export. The Storage account access is restricted to specifc trusted IP ranges and have enabled all "trusted microsoft services to access this storage account setting"

As per this https://docs.microsoft.com/en-us/azure/storage/common/storage-network-security#exceptions

O365 Ediscovery service/export route is not listed /considered as a trusted service. So need to specify the export routes' IP range explcitly for Azure storage firewall. Anyone else using this approach for export, Do we know if there a specifc IP range for Adv ediscovery export route ?

Thanks
