Slim 3 how to save JWT Token on local storage and use it in my routes for authentication

I want to implement jwt authentication for slim app, i followed tuupora’s PRS7 jwt authentication middleware and its working fine when i use Postman because there are options to use header as “Authorization: Bearer tokenString” as here bellow when i request “/auth/ibice” route

and am using the token string that returned when i request this route “/authtoken” as you see it bellow

{
  "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJ3d3cuYXNpZC5ydyIsImlhdCI6MTQ4Njk5MjcyNCwiZXhwIjoxNDg4Mjg4NzI0LCJjb250ZXh0Ijp7InVzZXIiOnsicGhvbmVubyI6IjA3ODQyMjY4OTUiLCJ1c2VyX2lkIjoiMSJ9fX0.1kFu4A16xxJriaRA9CccIJ3M9Bup06buK2LAh13Lzy4",
  "user_id": "1"
}

this my middleware.php that protect all routes of “/auth/”

<?php
// Application middleware
$container["jwt"] = function ($container) {
    return new StdClass;
};

    $app->add(new \Slim\Middleware\JwtAuthentication([
        "environment" => "HTTP_X_TOKEN",
        "header" => "Authorization",
        "path" => ["/auth"],
        "passthrough" => ["/authtoken"],
        "secret" => "your_secret_key",
        "error" => function ($request, $response, $arguments) {
                $data["status"] = "error";
                $data["message"] = $arguments["message"];
                return $response->withStatus(401)
                    ->withHeader("Content-Type", "application/json")
                    ->write(json_encode($data, JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT));
            },
          "callback" => function ($request, $response, $arguments) use ($container) {
          $container["jwt"] = $arguments["decoded"];
        }
    ]));

and my routes that i want to request with authorization header that is stored either from cookie or local storage but i have no idea how to do that!!

$app->group('/auth',function(){

 $this->get('/admin','App\Controllers\apiController:login')->setName('admin');   

//fetch ibice 
$this->get('/ibice','App\Controllers\apiController:ibice')->setName('Ibice');

//fetch ibice by id
$this->get('/igice/{id}', 'App\Controllers\apiController:igice')->setName('igiceId'); 

//search ibice
$this->get('/igice/search/[{query}]', 'App\Controllers\apiController:igice_search')->setName('Igice Search');

//imitwe igize igice
$this->get('/igice/{id}/imitwe','App\Controllers\apiController:imitwe')->setName('Imitwe');

//ingingo ziherereye mumutwe runaka
$this->get('/umutwe/{id}/ingingo', 'App\Controllers\apiController:ingingoBundle')->setName('Ingingo.bundle');

//ingingo ziri mucyiciro runaka
$this->get('/ingingo/icyiciro/{id}', 'App\Controllers\apiController:allstuff')->setName('Icyiciro');

//kuzana ikibazo kimwe kiri mungingo runaka
$this->get('/ingingo/{ingingoid}/question/{id}', 'App\Controllers\apiController:question')->setName('One_Exercise');

//kuzana ibibazo byose biri mungingo 
$this->get('/ingingo/{ingingoid}/questions', 'App\Controllers\apiController:questions')->setName('One_Exercise');

 //check if the answer is True or False
$this->get('/question/{id}/check/[{query}]','App\Controllers\apiController:checkQuestions')->setName('Check_Questions');

//get questions ids from ingingo
$this->get('/question/{ingingoid}','App\Controllers\apiController:questionsIDs')->setName('Check_Questions');
});
