On aliexpress for very cheap search for "DT3 Data Cable Detection Board Type-C". I got the one below and seems to work fine for what I needed.

Edit: This will test whether the cable is functioning properly. It will show the connections and indicate whether the cable supports only power or also data transfer. However, it won’t provide information about the USB-C cable type or its speed capabilities.
