How to restore icons on Samsung Galaxy Tab S2

I had to do a Hard reset on my tablet earlier today to resolve an issue with being locked out by the fingerprint software. While loading in all the apps again and sorting them on the desktop I accidentally deleted an entire page of icons when I thought I was deleting a single one by dropping it in the recycle bin at the top of the desktop. I didn't think it was possible to delete an icon like the settings feature, but I did, together with all the Microsoft icons and a pile of other stuff. I'm relatively new to tablets, so I don't seem to be able to find how to try an reset them on the home page, as I assume the programs are still on board and that it's just the icons that have disappeared. If I was on a PC I'd simply go into the menu or programs section and copy new shortcuts to the desktop, but because I no longer have access to the settings icon I can't open up the tablet to even list what programs I have on board - unless I'm missing something!

Can someone help point the way?
