Remove sentry plugin, how to?

Installed recently sentry-mattermost plugin, to realize is not working on latest sentry version, now my sentry shows this inside the sentry admin side:

That Nativeplugin without any details would be the mattermost plugin that does not work. On the other side we run in docker, so i removed all images and rebuilt it. The plugin is not present locally nowhere, yet this remained as in the image. Any ideas how to completely remove this view?
