facebook? Ik not eve related

Sorry, this totally isn't <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> related but I honestly can't find the answer and I'm genuinely curious! 
Not to sound like my grandmother but what does it mean when someone wants to share with you on facebook? Then like what are you supposed to do after you see the notification??? 
Thank you! Sorry again!
