Support scrollbar always visible

Would be nice to have an option to set the scrollbar to be always visible (X, Y or both). 

Tried to add it with css, but I can't seem to get it to work

`
"&::-webkit-scrollbar": {
            width: "4px",
 },
`
`
"&::-webkit-scrollbar-track": {
width: "6px",
 },
`
`
"&::-webkit-scrollbar-thumb": {
            background: "red",
            borderRadius: "24px",
          },
`
