Sharing icons

Hello,

I wish to add social media icons at the bottom of every ‘Latest posts’ on my website.

I can not find any options to do this and plugins I have downloaded don’t give me the option.

Here is a screenshot of what I want: https://imgur.com/EaP7dMP

As you can see below the ‘View Post’ there are several sharing icons. How do I do this? Is this a theme issue? This is on their latest posts on their front page, like mine.

Thanks,

Just Go Travelling
