How to make a variable VisibleAnywhere in a blueprint and not editable in a Details?

Hey,

I’m watching the tutorial about C++ coding – [BatteryCollector game video #11][1]
And there are a variable that made accessible from a blueprints but not editable via Details pane:

How can I add similar variable via Blueprints only (with no C++ coding)? I’ve tried some options (“Private” checkbox, “Editable” and so on – nothing helped; the variable still editable in the Details pane…)

There no way option for that in blueprints if it was it would be together with editable and private, feature request in feedback forum. Actully i seen similar quastion here about it recently
