There is in WP’s dashboard the Menu “Media” and two sub-menus (Library and Add New). I would like the possibility to embed a video from a provider (eg youtube) but there is not this option from this Menu. Could I customize the Media Library two include this posibility. How can I do it?

Thanks

First,

Please take some time to look up how to so, both here and in a generic search. It’s a stickler here when very well known and read topics are not simply entered into a generic search on search engines such as Google to find the result back here.

Next, know that there are many options to embed a video in WP. The easiest is to correctly copy and paste the URL into the Text Editor of your page or post and publish that post.
