How can I add social media buttons to banner on a main page?

Hello Everybody,

I would be more than grateful if anyone of you could help me with my issue.

I’m using Mesmerize theme and I’m trying to add social media icons (currently they are on the bottom of my website) to the banner under a text “Call us: + 357 96 318 700” on my main page.

I’m using a plugin “Social Media Follow Buttons” as far as I understood I should place this code “[smbtoolbar]” to add them, but I don’t know where exactly should I place it.

Could anyone help me?

ps: I’m new to WordPress, so in advance sorry if the answer for my question is obvious ??
