Yii2 many-to-many saving via link(), how to organize?

Question

Yii

I can’t find a normal example or a detailed description in the documentation, but I can’t understand it by parsing the code :) I
see the same example everywhere:
We define relationships in models

public function getMarkets() {
    return $this->hasMany(Market::className(), ['id' => 'market_id'])
      ->viaTable('tbl_user_market', ['user_id' => 'id']);
}

public function getUsers() {
    return $this->hasMany(User::className(), ['id' => 'user_id'])
      ->viaTable('tbl_user_market', ['market_id' => 'id']);
}

save models:

$user = new User;
$user->name = 'Foo';
$user->save();

$market = new Market;
$market->name = 'Bar';
$market->save();

$user->link('markets', $market);

But I can’t find the CRUD option where I need to save only the User and several Markets selected for it, the documentation is also far from clear, you end up feeling like I’m trying to find a solution by typing.
In general, please tell me how you can save links for many-to-many using link(), otherwise now all this is done in aftoSave in the model and it doesn’t look very nice.
