Add custom vocabulary to English model vosk-model-en-us-0.22 - STEP BY STEP GUIDE

Is it possible to add custom words to vosk-model-en-us-0.22 using Linux and then run the model in Python in Windows 10? The model is pretty good, but it does not recognizes properly names and company names that are not so well-known. Please anyone who knows may provide a step by step tutorial and post it here as I am new to Linux and things seems too complicated for me. I have read documentation but most stuff there are pretty hard for a new Linux user. Thanks.
