is there any way I could achieve prop-types combinations with ts

[mhesham32]

interface LoaderProps extends SpinnerProps {
    withModal?: boolean;
    // the below shouldn't be exisited if there is no Modal
    loadingText?: string;
}

so here I want a way to show type error when the user does this <Loader loadingText="Loading..." withModal={false | undefined} /> what is the direct way for doing this in React with ts.
