Using AppWarp S2, you can achieve this feature as it allows you to customise the server side code as well. AppWarp2 is on-premise solution where you get the server side SDK as well as Client side SDK. You can create your own server project using our SDK and customise the server as per your requirement. If you are already using AppWarpS2 then in the Room Adapter class you can write your logic to delete room after specified time using the delteRoom API.
Let me know if you have any further query, I will be happy to help.
