How can I make camera automatically change its location ,so that it would adjust to the models of different size?

Hey made some changes and I tried one thing where camera will go back to its original postion but i don’t know where I am getting wrong please check my blueprint

Took one pawn blueprints with spring arm
and one actor blueprint with a cube whenever i click on cube it will go to cube and with delay of 5sec need to come back to its position but it is not happening

Here my issue is camera is not coming back to its location
