Can I animate a skin texture using the Vroid Toon shader?

It’s basically the title.

I’ve been fighting with my model to get glowing tattoos with a scrolling effect. I got the tattoos to glow but I can’t find any resource to help me figure out how to get it have a glowing sweeping effect across them. Anytime I’ve tried to apply a different texture that I think will work the model turns purple and I can’t fix them unless I revert it.

Does anyone have any work around or resources that go over how to properly animate textures on a vroid VRM model?
