Call ads.create_pmax_campaign

Prepare a Google Ads Performance Max campaign — 'set up a performance max campaign', 'create a pmax campaign from our brand'. Create a Google Ads PERFORMANCE MAX campaign for this brand, with the asset group built from its saved words and pictures, and report the asset counts Google read back. Call it on the ask: it raises the approval card, which is the operator's confirmation, and nothing is created unless they approve it there. ⚠️ It is then created PAUSED and stays paused — you cannot start it, and nothing here spends the budget. Say so when you report it. Two saved things decide whether it can run at all: a bidding choice Performance Max accepts, and the Performance Max assets — ads.google_settings reports exactly which are missing. If missing_required_field_types comes back non-empty, say so: the campaign exists but the group cannot serve yet. Reuse the same idempotency_key on a retry — a fresh key mints a second campaign. Not for a Smart campaign — that is ads.create_smart_campaign. Over the API it answers in two calls: without confirmation_id it proposes — says what would happen, returns a confirmation_id and changes, spends and sends nothing; the same arguments again with that confirmation_id, on a member's own API key, do it.

Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with workspace_ambiguous and lists the choices — offer them, never pick one.
