Add Title (text) to Front Page

My front page of a business website doesn’t have a title – not so great!

The customize options don’t seem to offer anywhere to put it (I have added our name into ‘site identity’ but it doesn’t display).

This theme (snowfall) does not list the front/home page as one of my pages (so frustrating) – so I can’t edit it.

I don’t seem to have much ability to customize my home page in the wp dashboard – and unfortunately I don’t have experience to write code in (I’m learning very slowly!)

Is there a simple code I can add for my Title to display in the center of my front/home page?

Any help is GREATLY appreciated.
Cheers.
