I have seen quite a few posts over the years asking how to map something. In most cases you will need to learn how to use modifiers.
And it is very hard to explain in a forum.
It took me about a year to get good at mapping...there are many layers to what a person can do, but most importantly you have to figure out what works within a workflow and doesn't disable or interfere with the main hardware you use.
Here is a good example and introduction using modifiers...this isn't my video, but I thought it was a good starting point for anyone interested.
Not my video below but a good example.
