Does FB share button contain trackers?

I am considering putting a Facebook share button (shown below) on my website to encourage people to share content to their FB page.

fb share button

However, I do not want cross site trackers “bloating” my website or tracking users. This is the code I would need to put in the HTML to add the share button to my website.

<iframe src="" width="77" height="28" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowTransparency="true" allow="encrypted-media"></iframe>

Does this code contain trackers?
