Rhasspy 3 - Whisper - load new model

Hi, I am new to this community and need some basic help in setting up a rhasspy3 environment.

I want to use whisper as a stt application but I want to use a specific model for luxemburgish language.

I have the structure of the directory, but do not know how to integrate thos model into my config
The structure of the model is the following :

I would really like to get this work.
I need some guidance to integrate the model and use it from whisper, and then get the text out of the model to build an intent system

Any help would be welcome.
Thanks in advance Marc
