@abhijnyan-codes This seems like a syntax error:

Suggested change
tooltipProps?: Partial
tooltipProps?: Partial<

Omit<EuiToolTipProps, 'children' | 'content' | 'onMouseOut'>

}

interface EuiCopyState {
tooltipText: ReactNode;
}

export class EuiCopy extends Component<EuiCopyProps, EuiCopyState> {
static defaultProps = {
afterMessage: 'Copied',
};

constructor(props: EuiCopyProps) {
super(props);
export const EuiCopy = ({
