How Can I Creat Launcher for Dolphin

I have just installed 12.3 on my laptop with KDE desktop. There is a small launcher icon for Firefox in the bottom screen panel at the left near the “Kickoff” button. There used also to be a similar launcher for Dolphin but somehow I have deleted it. How do I re create this launcher in this position please.

open up Dolphin and right click on Dolphin in the taskbar and select “Show a launcher when not running”

Ether that or drag and drop

Perfect. Many thanks.
