How to set up icon display of plug-ins at tool bar

Can't find icon display from tool bar after updating Adobe Illustrator (AI) and reinstalled Plug-ins. How can they be displayed ?

Adobe Illustrator (AI) equips two types of tool bar. The one is "Basic toolbar" and the other is "Advanced toolbar".
If you cannot find the plug-in icons, the reason should be that you may set "Basic toolbar". Therefore, if you select "Advanced toolbar", the plug-in icons will appear.
To display the "Advanced toolbar," please click the menu button in the upper right corner of the panel displayed.
Then, please click the button shown "..." and select "Advanced".
