How to browse, an organized, textual list of commands that can be issued to Google Assistant

I was wondering whether there is any way (my guess, is that this would be almost like an exhaustive dictionary) to go though a textual list of all the Google voice commands you can issue to the Google app or to the Google Assistant app. Where can I find such a list? Can I find one on the system (perhaps, even within, the Google Assistant app itself, or, alternatively, within a special (related), app on the system)? Thanks
