How to check if a layer is a *video* group?

How can I check if a layer is a video group? “kind” for the layer is just returning “group” for me (not “video” as the enum would suggest). Is this a bug on Adobe’s side or is there a different way of checking for a video group? Thanks!

Did you look to see what is in that group’s layers property?

Yes. For both regular groups and video groups it gives me the children, but I cannot find a way to tell if it’s a video group vs a regular group, the child layers function the same way for both.

I also tried using Alchemist’s difference feature to look at the differences between a regular group and a video group:

It doesn’t look like there’s anything differentiating them, but maybe I’m missing something
