any way to add fully rigged unity accessories to a vroid model?

I’m assuming there is, I just have no clue how to do it. I’ve been sitting around at my pc for awhile trying to figure out how to attach some wings, antennae’s and neck fluff to a character, but it seems unity gets confused with it almost unsure what to do with the model because the items are rigged already.

Is there any way of doing this? Been lookin on the internet and I can’t really find a video talking about my kinda situation. Any help or advice is appreciated 🙏
