Hey, i'm having a problem to buy energy by steam. Does anyone know how to fix this problem? (the information is hard to understand since it is enable)

Its something like

CHECKOUT
Tha Steam overlay must be enabled in order to purchase energy. Please ensure that "Enable Steam Community In-Game" is checked in the Steam
"In-Game" settings, then restart the game.

xD if anyone can found a vid or made one that could help it would be nice to send it
Thanks ;)
