Discover command sent by app to configure a watch, using a packet capture app

I need help to Discover command sent by app to configure a watch, using a packet capture app like wireshark. I attaching packets i captured and attaching protocol to see commands structure. I need to know 2 commands sent by the app: Heart rate pulse request, and fall down notification alarm on/off and fall down call alarm on/off. I have a watch and i am making the app using commands of protocol document i attached. But no command to enable/disable fall down alarm. Company said me that is a secret file. But the company app has the option to enable/disable it, then, my goal is to see what command is sending the app, and then i will use the same command on my own app
