I got this mail from google a few months ago, there is some page that describing this deprecation?

Does September 13 is really the last day I can use "HTTP" schema in my services with google javascript OAuth ?

The mail:

Hello Google Developer,

We are writing to let you know that you have active OAuth redirect URIs and JavaScript origins in your Google Cloud project that are not in compliance with Google’s OAuth URI validation rules. All noncompliant active URIs will be removed, along with their origins, by September 13, 2021.

What do I need to do to be compliant? Please update your app and OAuth configuration in the Google Developer Console to use redirect URIs or JavaScript origins that are compliant with the OAuth URI validation rules by September 13, 2021.

The following Google Cloud project(s), which has/have registered URIs and origins that are out of compliance, and which will be removed if you do not update your OAuth flow to use compliant redirect URIs and Javascript origins by September 13, 2021:

Project ID: ************************ (DELETED) Client: ************************ (DELETED) URI: http://************************ (DELETED) URI: http://************************ (DELETED) URI: http://************************ (DELETED) If you have any questions or concerns regarding these changes, please review the documentation provided above in this email.

Sincerely,
