Badges can only be rewarded in Space packages, not in Space Templates. Check out the explanation of the difference between spaces and space templates here:
Spaces & Space Templates
Badges can be shared across multiple spaces if they are created from the same Unity Project.
Rewarding badges
As noted before, badges are rewarded when a user completes a quest. You can add a badge to the
Quest Rewards property on any quest. Select the type Badge and pick the badge you want to reward from the dropdown.
