React - how to change isOpen state? Do not mutate state directly. Use setState()?

Question

React

class Profile extends Component {
    state = {
        isOpen: false
    }
    

    render () {
        console.log(this.props.userss[0].name);
        (this.props.userss[0].name === "") ? console.log('не судьба') : this.state.isOpen=true;
        const body = this.state.isOpen && 
        <div> 
            <div>Name</div>
            <h3>
                {this.props.userss[0].name}
            </h3>
            <div>Number</div>
            <h3>
                {this.props.userss[0].number}
            </h3>
            <div>Login</div>

            </h3>
