I am following the documentation in order to show a NavItem only for screen widths larger than sm.
According to the documentation, I have to use this attribute:

I tried it here:
<NavItem className=".d-none .d-sm-block .d-md-none">
<NavLink
data-placement="bottom"
target="_blank"
title="Profile"
onClick={() => {
props.history.push("/profile-page");
}}
>
<i className="fa fa-bell " />
<p className="d-lg-none">Notifications</p>
</NavLink>
</NavItem>
But, this seems to have no effect. The navBar item (Notification Bell Icon) still gets displayed for widths larger than sm:
Any idea what I am doing wrong?
