Samsung Windfree A/C and Google Assist


I do have a windfree AC and I want to control it bij google assistant.
I cannot find any manual or forum item where the commands are worked out.
Some commands I found somewhere:
fan speed
mode (but not ‘auto’)

But a lot of others not:
sound on/off
light on/off
autoclean on/off
wind directions
options like quiet, comfort, fast turbo

Does anyone know where to find these commands?

Does realy no one know these things?
