Confluence Cloud OAuth 1.0 changes

I’m using OAuth 1.0 to authenticate on confluence cloud.

I have an developer instance (https://gabrielluiz.atlassian.net)

I’m using the endpoint below to get the request token:
/wiki/plugins/servlet/oauth/request-token

But this endpoint seems to doesn’t exist anymore, the endpoint has changed? It was deprecated? There is any configuration i need to do to activate oauth 1.0 (it was not needed before) ?

I can’t see any info on documentation about the Oauth 1.0 anymore, but it was working properly
