If you are on a computer or laptop, you can right click on your mouse. At the top of the options that appear, you'll see the Emoji option.

I use Windows Emojis and I get to them by clicking the Windows key [four squares] and the "period" key. It should bring up the box and you can select the category or there is a search box the you can type into, such as "smile", "flower", "heart", etc. When it brings up the box, after you have used it, it will bring up the most recent emojis you have used. I hope that is helpful. There may be easier ways, but I have used this method so long that it is my "go-to".
