How to change the previewImage of the Video ?

[yinghechen]

After I created a video through api, and I have the video ID, but I couldn't find a mutation that allows me to update the previewImage of the video. Or is there a way to set it during productCreateMedia or stagedUploadsCreate The documentation of video is at : https://shopify.dev/docs/api/storefront/2023-07/objects/Video

You should be able to update the preview image of the media with the productUpdateMedia mutation, `UpdateMediaInput.previewImageSource` is likely what you're looking for.
