Change the RSS feed image
I want to customize this part of WordPress feeds:
<image> <url>https://[example.com]/wp-content/uploads/cropped-logo-32x32.png</url> <title>My Site</title> <link>https://example.com</link> <width>32</width> <height>32</height></image>
There is a similar question with a wrong answer here. Changing media settings in wp-admin does not work.
I would like to change the image size or customize the entire part with a custom image URL for example.
