Extension icons (?)

I have installed a few extensions on my recently downloaded SU 2017 but I cannot find the way to place their icons on the screen. Any idea of how to do it?
It was so easy with SU 2016.
Thank you.

Not all extensions have icons but if they do you can find them by right clicking on the tool bar and selecting the extension there.

I just figure it out, right clicking on the area where the native icons are (top of the screen).
