How to respond to USSD Push | Telit Cinterion IoT Developer Community

Hello, This might be me failing to read the AT commands manual, but I could not figure out how to respond to a USSD Push or cancel the push. In this scenario, I am sending a network initiated USSD push (request or notification) to the module. I receive the push inside ATCommandListener { public void ATEvent(String inEvent) { But I cannot figure out which AT command to use to respond to the push. My aim is only to acknowledge the push notification from the handset: in this specific use case, the USSD Gateway does not expect any information from the Mobile Device. If the Mobile Device does not respond it causes the corresponding TCAP transaction to linger at the MSC/VLR/HLR/USSD GW for a few seconds. What is the AT command to respond the current Network Initiated USSD Request?
