How can the serial number of the AVEVA Edge softkey license running on a PC be identified?

The customer currently has an Edge runtime license and would like to add 1 additional thin client license to the existing runtime license. The orders team has asked for the serial number of the runtime license. However, the customer has multiple runtime licenses (Softkey) and is unable to determine which serial number is associated with which node. Could you please offer guidance on identifying the serial number of the license installed in the node?

Regards,
