Reactjs 如何在 TimePicker 中更改时钟 colored颜色 和确定按钮字体 colored颜色 MUI React

我正在try 使用css类名称属性更改TimePicker中的时钟 colored颜色 和确定按钮字体 colored颜色 等属性，但没有成功.有人知道如何使用SX或slotProps来改变它吗？

<TimePicker
          ampm={false}
          views={['hours', 'minutes', 'seconds']}
          sx={{
            backgroundColor: "#333335",
            font: "white",
            color: "#FFFF",
            textDecoration: "bold",
            input: {
              color: "#FFFF",
              fontSize: "1.4rem",
            },
              "& .MuiTimePicker-root": {
              backgroundColor: "#222223",
            },
            "& .MuiTimePicker-input": {
              color: "#FFFF",
              fontSize: "1.2rem",
            },
          }}
          slotProps={{
            popper: {
              sx: {
                "& .MuiList-root": {
                  backgroundColor: "#333335",
                },
                "& .MuiMenuItem-root": {
                  "&.Mui-selected": {
                    backgroundColor: "#04395E",
                    color: "white"
                  },
                  color: "white"
                },
                "& .MuiDialogActions-root": {
                  backgroundColor: "#333335",
                },
                "& .MuiSvgIcon-root": {
                  "&.MuiSvgIcon-fontSizeMedium": {
                    backgroundColor: "#04395E",
                    color: "white"
                  },
                  color: "white"
                },
              },
            },
          }}
          value={selectedTime}
          onChange={(newTime: any) => setSelectedTime(newTime)}
          timeSteps={{hours: 1, minutes: 1, seconds: 1}}
/>

Here's a image showing the elements that I want to change the color
