Acces to the "Emitters action windows" in Niagara

Hi ! I’m trying to setup a fire particle effect with Niagara but i can’t find the “Emitters action windows”. In each tutorial i watch, the right click on the node works and the Emitters actions windows appears

But Nothing is happenning when i right click on this windows. I looked for the options otherwise but I can’t find anyway

Someone would have any idea ?

In screen, the windows option i’m looking for.

After creating a Niagara System in your content browser, double click it to open it. (Let’s say FX=>Niagara System=>New sytem from template=>Simple Explosion):

If I left click on one of the emitters, all important options are shown on the right side. The Selection category is visible when you go to Window in the upper left and activate Selected Emitters

There you can also access the menu which is shown when you right click an emitter => just left click the Gear symbol which is marked in the picture (red box).
