How can I use facebook sdk to share a link or a picture?

Hello my friends,

I am trying to implement a simple facebook share button in my app where I am able to click it and share, for example, a link or an image.
I want to apply what is described here : https://developers.facebook.com/docs/sharing/android?sdk=fbsdk
So far so good I had been able to perform a login using expo-facebook and its login feature, however I dont know how can I use the facebook-sdk to share stuff. I already ejected the application and added the provider tag on the anndroidmanifest.xml as instructed on the link above.

Does anyone have experience on this or know how can I accomplish it?

Thanks in advance for any help!
