How do I add a video splash screen in Unity

Good day and Helloy connoisseurs! Please help or explain how to play a Video splash screen (ogg) in Unity3d. Assume that there is a shortcut to the extension exe you click 2 times and runs this video splash screen 1 35 seconds and then provides you to the game menu. Write here or me in the plumbing (HTTPS://VK.COM/DARK0R) or give the site, forum, or video YouTube. My version of Unity3d f Thank you in advance

Make a separate scene where you will run the video/animation and make it the first scene in your project, and after it is done switch to your next scene, which is probably the menu.
