add shortcode to toggle content

Please add the following shortcode at ‘/doccheck-login/client/class-dcl-shortcodes.php ‘
add_shortcode( 'dc-toggle-content', [ $this, 'dcl_shortcode_toggle_content' ] );

        /**
         * Shortcode: toggle content.
         *
         * Toogles content between brackets for DocCheck users.
         * If Users logs in, then Content is hidden
         *
         * [dc-toggle-content]Hidden content[/dc-toggle-content]
         *
         * @param   $atts
         * @param   null $content
         *
         * @return  string
         * @since   1.0.0
         * @access  public
         */
        public function dcl_shortcode_toggle_content( $atts, $content = null ) { 
                if ( $this->dcl_has_logged_in_user() ) { 
                } else {
                        return wpautop( $content );
                }

                return ''; 
        }

This way we are able to add custom messages for non logged in users and won’t bother logged in users.

And please, please move this plugin from SVN to GIT ??
