Where is my link icon

when sending a link to our instance over whatsapp or whatever, how do we change the icon that shows up when whatsapp makes a link preview? we’ve replaced the favicon, the logo, as well as all the different icons in the icon folder. still no joy. is there another place whatsapp can find an icon to preview?

In the next version social media should use the squared instance icon that you set in the admin interface

thank you for stopping in

my bad. that was a channel icon, not an instance icon.
