H5PMod : Apply to all h5p libraries

Hello,

I'm looking for code that will apply custom.css to all the H5P libraries that are installed in Moodle.

The default code below only add custom.css to interative video : 

Thank you! 

    public function hvp_alter_styles(&$styles, $libraries, $embedType) {
        global $CFG;
        if (
            isset($libraries['H5P.InteractiveVideo']) &&
            $libraries['H5P.InteractiveVideo']['majorVersion'] == '1'
        ) {
            $styles[] = (object) array(
                'path'    => $CFG->httpswwwroot . '/theme/h5pmod/style/custom.css',
                'version' => '?ver=0.0.1',
            );
        }
    }

    /**
     * Add scripts when an H5P is displayed.
     *
     * @param object $scripts Scripts that will be applied.
     * @param array $libraries Libraries that will be displayed.
     * @param string $embedType How the H5P is displayed.
     */
    public function hvp_alter_scripts(&$scripts, $libraries, $embedType) {
        global $CFG;
        if (
            isset($libraries['H5P.InteractiveVideo']) &&
            $libraries['H5P.InteractiveVideo']['majorVersion'] == '1'
        ) {
            $include_file = ($embedType === 'editor' ? 'customEditor.js' : 'custom.js');
            $scripts[] = (object) array(
                'path'    => $CFG->httpswwwroot . '/theme/h5pmod/js/' . $include_file,
                'version' => '?ver=0.0.1',
            );
        }
    }
