Access PROTON in terminal

how do we access proton from the terminal.
I run:

env WINEPREFIX="/home/user/Games/star-wars-jedi-fallen-order" WINEPATH="/SteamLibrary/steamapps/common/Proton 5.0/dist/bin/wine64" winecfg

And my system WINE always comes up.

Never mind found it. was using the wrong command. Must be PROTON and not WINEPATH.
