UE5 BlueScript - Save activation buildings

I need a code that will store the activations of all buildings in the game.

An example is in the picture
When he gets too close to the console, a widget opens
if he clicks ok, the decision is saved, and if he clicks several times, the button is not active any more
and prints the buildings working or buildings are activated

if it is not ok x, the parameters are deleted and the building does not work.

It is necessary to work in
UE 5 and Blueprint

I will send you the code
BP_ECHO - character and
overlap sphere code - when the character gets too close to the building
