Update Subscription. How i can use update?

Hello Beno!t POLASZEK. I see the WebPushClientRegister.updateOptions option, but the controller lacks the answer to the PUT request method. Could you please help update the webpush-sw.js file every time a user logs on? I would like to avoid a situation in which we modify this file and there is an old file on users' computers.

Thank you very much for your answer.
