Avada Theme related query

We have recently developed a website for a client using Avada Theme and when forwarded the website URL to the client via WhatsApp, I have noticed something, which is attached as a screenshot. There is an “intro” text appearing “MG Logistics provides professionally managed…”, I would like to add a customised new text instead of the current text. Please can someone advise me on how to change it to my own text. Many thanks.
