Rendering a new component inside componentDidMount - React

I will have to render a new component after all the expected components are loaded. I will need a timeout based on which the the new component has to be rendered. So this new component has to show up after 5 minutes after the page has loaded. I need to render a component called new_component that extends React.component

public componentDidMount(): void {
      if (visited) {
      setTimeout(() => {
        console.log('Reached the timeout')
        //Render the new conponent here. (Not sure how to call the render function of another component here)
      }, timeout);
    }

Can someone help me call the render function of new_component inside componentDidMount please. i tried new_component.render(). But that does not seem to work.

You can use state to track this.

componentDidMount() {
    setTimeout(() => {
        this.setState({ showNewComponent: true })
    })
}

and in render:

render() {
    if (this.state.showNewComponent) {
         return <NewComponent />
    }
    return null
}
