Changing the favicon on volto

I added a favicon to the backend in Setttings/Site and replaced the favicon.ico in frontend/public but I still get the plone favicon on both firefox and chrome. Any idea what I'm missing?

You have to also do the public/icon.svg

Thanks @tiberiuichim, that works.

Just a heads up on SVG, I struggled to successfully convert my png and ico files to svg using ubuntu and online tools until I found PNG to SVG (Free, Full Color) - SvgTrace which keeps the original colours intact.
