Not all manually installed IDE's are shown in the ToolBox

Hello,

recently I installed the ToolBox. With the default configuration the ToolBox recognizes manually installed PhpStorm but not IntelliJ IDEA Ultimate.

IntelliJ and PhpStorm are in the same directory with the same permissions (/opt).

Could you give me a hint how to tell the ToolBox to recognize the other IDE too?

ToolBox Version: 1.15.5605
