OK, but how navigate inside function eventClick, like :

  eventClick = () => {
    this.props.history.push('/addons');
}

You can use Link/NavLink component like a button or use these components like wrappers to button and add a click event handler to Link.

                 <MDBNavLink
                    tag='button'
                    to='/addons'
                    color='mdb-color'
                    className='btn btn-outline-mdb-color btn-sm btn-rounded d-inline'
                    onClick={this.eventClick}
                  >
                    More
                  </MDBNavLink>
