What's the list of HA commands in french?

it seems there is no french (or dutch) version of

(https://assistant.google.com/u/1/explore/c/19/?hl=fr-FR)
Does anyone has the corresponding french keywords?

regarding the use of custom commands, is it correct those have to be created manually as ‘routine’ in Google assistant?

Is there a way to keywords form the commands like ‘dans’,‘à’,‘au’,‘le’,‘la’,‘les’,‘l’,’’’,‘lumière’,‘lumières’,‘du’,‘des’,‘de’,‘sur’
that sometimes are added and eventually refer to the same light… ?

Where can I troubleshoot and see the commands sent from Google -> Home asssitant?
In the logs I can find errors,.
When sending a command on a group of lights (via mochad X10)I have the same (timeout?) issue, like Google Home unknown error?
‘something went wrong’ , (erreur inconnue)

tx!
