How to set a session flash message in lumen 8?

[Osman-Rafi]

I am trying to set a session flash message in blade file in lumen 8. However it's stated a pervious version but not present in latest doc.

Here is my code snippet

In Controller:

public function foo()
{
  ....
  return redirect('contact')->with('status', 'Message sent successfully !');
}

In blade:

@if (session('status'))
    <div class="alert alert-success">
        {{ session('status') }}
    </div>
@endif

But it's not working & throwing an error
Call to undefined function Session()

How can I set a flash message in blade after redirect ?
