google not indexing my videos properly

Hi, I generate a sitemap at this url (cant seem to post the url here so I'll add in comments), I have submitted this via the google search console, google parsed it and states that there are no errors, it also states that it founds175 URL's which is correct.

A couple of days later the URL's got indexed, but not as videos. If I search for site:gaze.cash I can see them all but as regular links whereas I expect them to be under "videos" with their thumbnails etc.

Any idea what I could be doing wrong?
