Widget Footer Putter mail adress encode

Hi,

I can’t get EAE to work with the plugin Footer Putter in the copyright widget:
https://wordpress.org/plugins/footer-putter/

I’ve tried to add a filter as a snippet:
add_filter( 'widget_footer', 'eae_encode_emails' );
or
add_filter( 'footer_copyright', 'eae_encode_emails' );
and several others but it doesn’t work…

Probably I don’t get the right filter? Do you have any idea, what I could use?

Thanks in advance
Chris
