How does Google Search console want to improve video?

Question

YouTube

Google Search console sent notifications that supposedly I have problems on pages where there are regular iframes with Youtube videos:
- the "thumbnailUrl" field is missing
- the "name" field is missing
- the "description"
field is missing - the "uploadDate" field is missing
Means Is it that I have to manually customize all YouTube inserts so that they comply with the standards? And why did Google need all this all of a sudden?

Answer 1

To use these words to find your application in the search, and direct more users to you
thumbnail URL - I guess the picture is a preview of the video.
