UE5 EA ToolBar Button extension missing

I make my plugin upgrade from 4.26 to the UE5 EA version! But I can’t find it in the toolbar place! I also made a toolbar button plugin from the UE5 Early Access version, While I can’t find the button from the Toolbar area! Looking for help!


As I understand the menu’s name for the toolbar is changed in the UE5, so you can register your new toolbar button on the new toolbar name.
