Create a new ad group under a campaign. Every ad group belongs to one platform (body.platform, a platform id such as google-ads): only that platform receives it, its ads and its keywords. Leave it out on a campaign that runs on one platform; name it on a campaign that runs on several (400 AD_GROUP_PLATFORM_REQUIRED lists them). It is fixed once created — use copy_ad_group to run the same ads elsewhere. Returns the full updated/created object. Scoped to the active Space — see set_active_space to switch, or pass space_id to override for this one call.
