How to set behavior for controllers in a module in Yii2?

Question

Yii

I have created a rest api module and I need to assign behaviors to all controllers in this module. The behavior is:

$behaviors['contentNegotiator'] = [
    'class' => ContentNegotiator::className(),
    'formats' => [
        'application/json' => Response::FORMAT_JSON,
    ],
];

Naturally, I put it all into the behaviors method, first returned the parent behavior and added a new one.
If I add it to the controller, then everything works fine and the data is returned in json format, if I add it to the module, then nothing works. So the question is, is it really possible to set behaviors for controllers in a module, or do you need to create a parent controller, inherit it from the rest controller, define behavior in it, and then inherit your controllers from this controller?

Good morning.
Try adding the behavior file to the bootstrap section in the config file

'bootstrap' => [
'app\modules\name_module\YoumoduleBootstrap'
]

FILE YoumoduleBootstrap implements BootstrapInterface
