Session Data Missing For Test

I'm trying to figure out what I'm doing wrong in my test. Currently my test passes until it hits the assertSessionHas('company_id', null) part of the test. Currently the test is failing due to Session is missing expected key [company_id].

I go through the browser and I see the company_id in the session. Not sure what I"m doing wrong.

/** @test */
    public function a_super_admin_who_impersonates_a_company_admin_can_leave_impersonation()
    {
        $superAdmin = User::factory()->superAdmin()->create();
        $user = User::factory()->companyAdmin()->create();

        $this->actingAs($superAdmin)
            ->post(route('impersonate', $user))
            ->assertSessionHas('company_id', $user->company->id);

        $this->assertAuthenticatedAs($user);

        $this
            ->get(route('leave-impersonation'))
            ->assertRedirect()
            ->assertSessionHas('company_id', null)
            ->assertSessionMissing('impersonate');

        $this->assertAuthenticatedAs($superAdmin);
    }

/**
     * Handle the incoming request.
     *
     * @param  \App\Models\User $user
     * @return \Illuminate\Http\Response
     */
    public function destroy(User $user)
    {
        if (! session()->has('impersonate')) {
            abort(403);
        }

        $impersonator = User::withoutGlobalScope(CompanyScope::class)->find(session('impersonate'));

        auth()->login($impersonator);

        if ($impersonator->hasRole('super-admin')) {
            session()->put('company_id', null);
        }

        session()->forget('impersonate');

        return redirect()->route('user.dashboard');
    }
