Can't make an animated GIF with the layers grouped to apply fx

[Khalaris]

I was so excited to use layer group fx to make nice looking animated gifs, but when I try to export, the dialogue tells me it can't animate because there's only one layer

Is there a way to apply the fx of the layer group to all layers? Then I could remove the group and export normally.
Or maybe make the export function resolve the grouped layers with their fx?
