Create Many to Many Polymorphic Relationship using custom table

How can I create a Many to Many relationships using the custom polymorphic table?

model_has_tags

$table->increments('id');
$table->integer('tag_id';
$table->string('model_type');
$table->integer('model_id');

tags

$table->increments('id');
$table->string('name');

user

$table->increments('id');
$table->string('full_name');

I try this but not working. Tag Model

public function users()
    {
        return $this->morphedByMany(User::class, 'model')->using(ModelHasTags::class);
    }

User Model

public function tags()
    {
        return $this->morphToMany(Tag::class, 'model')->using(ModelHasTags::class);
    }

error :

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'stormport.models' doesn't exist (SQL: select `tags`.*, `models`.`model_id` as `pivot_model_id`, `models`.`tag_id` as `pivot_tag_id`....

How to solve this?
