Show video before loading site?

Question

Video

Good afternoon! We really need your help! Can you please tell me how to add a video so that it is shown before loading the site page? I tried the Very Simple Splash Page plugin, but it does not work correctly on my site, apparently because it was not tested with the wordpress version. Maybe there are some analogues? The site itself is on elementor. You can try to do it through the code, but I'm not very strong in this, so it would be nice to read a more detailed explanation on this topic. In general, I will be grateful for any help in this matter or advice ... Thanks in advance to everyone for the answers!
