How to add videos to video album

Hi,

probably really a dumb question. But I am not getting the installation instructions (https://www.ads-software.com/plugins/utubevideo-gallery/#installation).

How do I
4. Create video albums for gallery just created.
5. Add videos to video album just created.

? Don’t see anything similar to this. I see ?Gallery? and ?Playlist?. But no ?video albums?.

Could anyone give me a hint?

Thanks a lot!
