Set the business name asset

Creates a text asset holding the business name and links it as the BUSINESS_NAME asset of a campaign (or of the account). Use when: you are building a Performance Max campaign, or a campaign is missing its business name. Do not use when: the campaign already has one — Google allows a single business name per campaign and a second link is rejected. Check google_list_assets first. A business name is linked to a campaign or to the whole account; Google has no ad-group-level business name, so passing ad_group_id is refused with that explanation instead of failing at Google. Google requires advertiser verification on the account before a business name asset can be used; without it the call comes back CUSTOMER_NOT_VERIFIED. That is the account's state, not the arguments: tell the user to finish verification in Google Ads and do not retry with different text. The name is 25 characters or fewer and should be the business as customers know it, not a slogan. An identical name already linked at the same level is skipped. If you are unsure which account, campaign or period the user means, ask them — do not guess ids or dates.
