Screenshots

Before

After

Could use the outlined version which looks same as before, but we need to add for it. Since other icons are not using the outlined version, I'm wondering if we could use rounded version for this

Looks more rounded than before

The edit and delete icons look a little bit different

The filled area is flipped

The collection icon is more rounded and the chat icon has a shorter line at bottom
