laravel backend page not found - laravel

Question

This is vuejs and laravel project. I am facing issue in backend when I type complete url with admin then it says not found. This is happening because I was getting 404 laravel error in refresh inside components. So I used the below route in web.php
Route::get('/{any?}', function () {
return view('index');
});
In Vuejs, I am using the following:
I am using webhistory in route
I am also using fallback route
{
path: "/:pathMatch(.*)",
name: "NotFound",
component: NotFound,
},
backend is based on laravel. Here is the .htaccess data
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
RewriteEngine On
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Send Requests To Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
laravel route
I tried the below one:
Route::get('/{any?}', function () {
return view('index');
});
and this one also
Route::get('/{any}', function(){
return view('index');//pointing to the index file of the frontend
})->where('any', '.*');
Route::get('/admin',[AdminAuthController::class,'Create'])->name('create.login');
Route::post('/admin/login',[AdminAuthController::class,'Store'])->name('store.login');
Please suggest
