Hi Team,
Thank you for the clarification regarding image assets. Could you please help me understand how I can link a *video asset* with a campaign via the API? Specifically, I would like to know: 1. Which *campaign types* support video assets? 2. What is the correct approach to *link a video asset* to a campaign using the Google Ads API? 3. What AssetFieldType should be used for video assets in such cases? Your guidance on this will be really helpful.
