Commando to IPTV box

[MMSoft 0]

I am trying to create a remote control app for my Android phone to control an (Android) IPTV box.
When I test it on the PC (in the command prompt screen), it works:

C:\ADB\adb.exe connect 192.168.178.44
Gives:
connected to 192.168.178.44:5555
 
And these commands also work:
C:\ADB\adb.exe shell input keyevent KEYCODE_DPAD_DOWN
C:\ADB\adb.exe shell input keyevent KEYCODE_DPAD_UP
C:\ADB\adb.exe shell input keyevent KEYCODE_DPAD_CENTER

But how can I get this working in Delphi 12.1 FMX Android ?
