Setting the width of the Material drawer same as child in React

Question

I am trying to modify the width material drawer example provided in their official document https://mui.com/material-ui/react-drawer/#permanent-drawer.

How can I set Material Drawer width to the width of its children in Reactjs? As I only wish the navbar to show material icon only but not the text.

Currently, the example uses a constant value to define the width of the drawer. I would like to remove that

const drawerWidth = 200;
      <Drawer
        sx={{
          width: drawerWidth,
          flexShrink: 0,
          "& .MuiDrawer-paper": {
            width: drawerWidth,
            boxSizing: "border-box",
          },
        }}
        variant="persistent"
        anchor="left"
        open={open}

I tried to remove the const drawerWidth = 200; but the whole drawer thing is broken. I am new to Mui, any help is appreciated.
