Removing Oauth server

Hi there,

I\m pretty new to the Oauth authentication and I misunderstood how the Oauth server works. Now I would like to remove it, but I can’t seem to find any info on how to de-install it. There’s no button at the filter-page in WP and I’ve try to find it in this forum and on the site of Oauthserver but I can’t find it.
Can anyone tell me how to remove the WP Oauth server? Or redirect me to the documentation?

TIA
Marco
