Wordpress - Insert icon next to text

Question

I'm new to this frontend area (freelance backend) and I needed some help. I simply need to put that WhatsApp icon before the phone... But I'm taking a hell of a chorus (missing Java... lol)

Can someone give me a help???? With this code the visualization is like this...

[icon name="theme-screen-smartphone" style="" color="accent1" size="50" ]
<h1>ATENDIMENTO VIA<strong> WHATSAPP</strong></h1>
