Icons
The MaterialUi icons do not have separate bindings. There is a good reason for this: Bindings result in thousands of files (or one extremely large one), which take a good while to recompile (easily upwards of one minute, this is unacceptable performance for a ReScript project).
It is therefore recommended to bind to the icons you need manually. See the following example for how this could look like:
module SupervisedUserCircleOutlined = {
    @react.component @module("@material-ui/icons/SupervisedUserCircle")
    external make: (
        ~color: string=?,
        ~className: string=?,
        ~fontSize: string=?,
    ) => React.element = "default"
}
@react.component
let make = () => {
    <SupervisedUserCircleOutlined color={Mui.Colors.red.c400} fontSize="26px" />
}
