Jira Cloud Rest API authentication with cloud.session.token

Hi, guys!
Here is deprecation notice https://developer.atlassian.com/cloud/jira/platform/deprecation-notice-basic-auth-and-cookie-based-auth/.
Does this also apply to cookie-based authentication in the same browser? When we open multiple JIRA windows, they have a cloud.session.token cookie. And it works. Get request for endpoint /rest/auth/1/session, returns status 200. And we have access to all endpoints.
Can we continue to use this way?
