PAT on Mac (Ventura) w/TS-590s sends wrong PTT type

[CM9067]

I'm using Pat on an intel based Mac running Ventura. This is connected to a Kenwood TS-590s radio. The TS-590s needs to receive a PTT=3 (cmd=TX1) in order to send data using the USB connection between the radio and the computer. Pat for Mac OS sends a PTT=1 (cmd=TX), which is the front mic. How can the Pat for Mac OS be configured so that a PTT=3 command is sent instead of the PTT=1?

Thank you for your time.
