How can I change the mune on the left?

I have this piece of code in
layout > demo7 > aside > __tabs.blade.php
Where are the @foreach(theme()->getOption('menu', 'aside_tabs') as $tab)
value set?

Thank you

<!--begin::Nav-->
<ul class="nav flex-column">
@foreach(theme()->getOption('menu', 'aside_tabs') as $tab)
<!--begin::Nav item-->
<li class="nav-item mb-2" data-bs-toggle="tooltip" data-bs-trigger="hover" data-bs-placement="right" data-bs-dismiss="click" title="{{ $tab['tooltip'] }}">
<!--begin::Nav link-->
<a class="nav-link btn btn-icon btn-active-color-primary btn-color-gray-400 btn-active-light {{ $loop->index === 1 ? 'active' : '' }}" data-bs-toggle="tab" href="#{{ $tab['link'] }}">
{!! theme()->getSvgIcon($tab['icon'], "svg-icon-2x") !!}
</a>
<!--end::Nav link-->

<!--end::Nav item-->
@endforeach

<!--end::Tabs-->
