How can I remove one of my plugins from the WordPress Plugins Directory. I think I did something wrong, so I add my plugin twice. Here’s the plugin which needs to be deleted: https://wordpress.org/extend/plugins/pingmk-share-button-mk/.

They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party’s page?
