How to render Vue component in hidden HTML element

In my app, I have the right slide bar that contains Vue components that represent system notifications. By default, the right bar is hidden (out of the screen) and when the user opens it the bar is blank(meaning no components displayed). In DevTools, I can see that Vue components weren't rendered

However, if I put the same code from right.blade.php to any normal view then every notification will be displayed.

My assumption so far, the Vue cannot render components in hidden HTML. Am I correct?

Here is the screenshot that demonstrates the presents of PHP code and the absence of Vue component, and the code itself:

rightbar.blade.php

<div id="rightbar" class="rightbar">
    <div class="mt-2">
        <ul class="nav nav-tabs2">
            <li class="nav-item"><a class="nav-link active show" data-toggle="tab" href="#notifications">Notifications</a></li>
            <li class="nav-item"><a class="nav-link" data-toggle="tab" href="#channels">Channels</a></li>
        </ul>
        <hr>
        <div class="tab-content">
            <div class="tab-pane show active" id="notifications">
                @foreach(auth()->user()->unreadNotifications as $key => $notification)
                        <p>here</p>    //<---------------------------this works
                        <notification props_id="{{$notification->id}}"
                                      props_route="{{route('item.show',$notification['data']['item']).'#documents'}}"
                                      props_title="New item uploaded"
                                      props_body="User {{$notification['data']['name']}} uploaded {{$notification['data']['item']}}"
                                      props_date="{{$notification->created_at}}">
    
                        </notification> //<------------------------- this doesn't works
                @endforeach
            </div>
