Adding custom tab with functionality of another plugin

I’d look at using the bp_before_has_profile_parse_args filter like I how I use it in the plugin:

add_filter( 'bp_before_has_profile_parse_args', array( $this, 'filter_tabs' ), 10, 1 );

/**
	 * Filter the tabs to show on the member page
	 *
	 * @param array $args Tabs arguments.
	 *
	 * @return mixed
	 */
	function filter_tabs( $args ) {
		if ( isset( $args['exclude_groups'] ) ) {
			$args['exclude_groups'] .= $this->tabs_to_filter;
		} else {
			$args['exclude_groups'] = $this->tabs_to_filter;
		}

		return $args;
	}

In this case I am excluding tabs but perhaps there is a way to include new ones, it is not something I’ve looked into before.
