Unfortunately, only search and display campaigns are supported in the standard campaign selector.
For other campaign types you should use the specific selectors (such as ShoppingCampaignSelector for shopping , VideoCampaignSelector for video campaigns, and PerformanceMaxCampaignSelector for Performance Max campaigns).
Aside from those, the following campaigns are not yet supported in any campaign selector within Google Ads scripts:
- discovery
- local campaigns
- Demand Gen
For now, you can only retrieve data for these campaign types via AdsApp.search / report.
