Update: New icon got reverted back.
It turns out that Snapchat has a new icon for lenses and a lens creator explore page. The icon itself looks like a face mask emoji. As for the exploring section, it has a "creators" tab where you can see a row of filters by creators you subscribed for.
Below that, there is a recommendation section named "creators for you". This was spotted in the recent beta build v18.104.22.168 but possibly was available before for some users.
