Hi @hamzadwaya,
Thanks for your offer and sorry for long response.
I've added you as co-maintainer of this project.

Video sources are based on plugins. You need to create a plugin in your custom module for wistia viedo source, which extends VideoLocationPluginBase. You can check VideoFile plugin as an example in src/Plugin/video_sitemap/VideoLocation/VideoFile.php.
