How to add Whatsapp launcher icon to 'dock' ?

[Externet]

Hi.

Installed? Whatsapp to new drive with Ubuntu 24.04 on my laptop and it is functional.  Find no launch icon,  have not closed the tab until solving.   On previous hard drive it did show at the bottom of screen.  Does not show listed in 'installed' applications !

I have only Brave browser working perfect, cannot find how to implement the launcher (or is it favorites?).   Help in wording for the unskilled, please.

I followed this to install :

If it shows "Remove from favorites" is because it is already in the favorites list, right ?

 

Well, cannot see it at the bottom.
