Deprecated warnings on PHP8.2

When using the PHP 8.2 version, WP 6.2.2 and review stream plugin in its latest 1.6.6 version, it throws some deprecated warnings, wondering if there is work considering that issue.

An example of this issue:

Deprecated: Creation of dynamic property ReviewStream::$brand is deprecated in /wp-content/plugins/review-stream/reviewstream.php on line 175
