Why my JetBrains Toolbox can't find my IntelliJ IDEA which has been installed already?

Question

I installed JetBrains Toolbox, but it cannot show the IntelliJ IDEA I installed before. Also I cannot open the local projects on the toolbox via IntelliJ IDEA, while WebStorm, DataGrip and CLion I installed before are available.

Is there anything I need to do with the toolbox or the IntelliJ IDEA?

expecting: I can use my IntelliJ IDEA normally via JetBrains Toolbox.

Answer 1

Could you clarify is it also displays the IDEA in the control panel in the uninstall program? If Windows shows it correctly, Toolbox App should show it too.
