Can not use this.props.history.push()

Question

 saveEmployee = (e) => {
        e.preventDefault();
        let employee = { firstName: this.state.firstName, lastName: this.state.lastName, emailId: this.state.emailId };
        console.log('employee => ' + JSON.stringify(employee));

        EmployeeService.createEmployee(employee).then(res => {
            this.props.history.push('/employees');
        })
    }

I am using react-router v6 and know that it removed history.push().What should I do? I used navigate() but don't know how to use it, maybe I used wrong.Pls help me
