Video Sitemap

Hello,

In connection with optimising the indexation of my domains, I was considering that having better structured data and a video sitemap might help me in this regard.

With respect to the video sitemap, in a nutshell, I do not understand, once created, what are the next steps, is it necessary to submit this new sitemap in the various search engines as done in the past with the classic sitemap, for example in goodle search console, bing etc.etc..

Or once created, does this complement the classic sitemap and, in fact, no such action is necessary?

Best regards
