I have this red number 1 next to my file manager in Fedora 38. No clue what it means or how to fix it

Hello all, I am brand new to fedora, so Im still learning the ropes. I've been noticing this red number 1 next to the file manager in the dock. Being a debian/ubuntu guy at heart, I don't quite know how to troubleshoot this. Hope you guys can shed some light; pic is below!
