Remove RSS Feed Image

Hello I want to remove image from the RSS Feed and I only see the summary of the podcast. In previous versions of the plugin I found the string to remove in the feed-item.php file:

@var Frontend_Controller $ ss_podcasting
global $ ss_podcasting;
$ episode_image = $ ss_podcasting-> get_episode_image_url (get_the_ID ());
$ episode_image = apply_filters (‘ssp_feed_item_image’, $ episode_image, get_the_ID ());

But now I can’t find the string anymore, I kindly ask how to remove the image now

Thanks
